Description

Technical Field

[0001] This application relates to the technical field of machining, and in particular to a quick-change tooling for accelerating chamfering. Background Technology

[0002] In the field of machining, sprockets are crucial transmission components, and their quality directly impacts the performance and reliability of the transmission system. To meet the lightweight design requirements of sprockets, multiple weight-reducing holes are typically formed on their circumference. A center mounting hole is located at the center of the sprocket's end face, and multiple locating pin holes for assembly are evenly distributed along the circumference of the sprocket, situated between the center mounting hole and the weight-reducing holes. To ensure smooth assembly of the locating pin holes, chamfering is performed on both sides of the holes.

[0003] In related technologies, a combination of drilling and manual handling is typically used to chamfer both sides of the locating pin holes on a sprocket. First, the sprocket is placed on the drilling machine manually, and the position of the locating pin holes is manually adjusted to align with the chamfering tool. Then, the drilling machine is started to drive the chamfering tool to chamfer the locating pin holes. Because there are many locating pin holes on the sprocket, the sprocket needs to be rotated manually multiple times during the processing, and each locating pin hole is chamfered sequentially by the chamfering tool. After processing one sprocket, it needs to be manually removed and replaced with a new sprocket to be chamfered, and this process is repeated.

[0004] In practical use, it has been found that because the parts need to be rotated frequently by hand for chamfering of multiple holes, the labor intensity is high, the production stability of sprockets is relatively poor, the efficiency is low, and it is difficult to meet the needs of mass production. Summary of the Invention

[0005] To improve the processing efficiency of sprocket chamfering, this application provides a quick-change tooling for chamfering acceleration, which has the effect of improving the processing efficiency of sprocket chamfering.

[0006] This application provides a quick-change tooling solution for accelerating chamfering, which adopts the following technical solution:

[0007] A quick-change tooling for chamfering acceleration includes a tooling base plate. Multiple workstations are arranged on the tooling base plate. Each workstation is equipped with a material placement platform and multiple clamping components. The multiple clamping components are located around the material placement platform. A positioning post for passing through the center mounting hole of a sprocket is vertically arranged at the center of the material placement platform. The height of the positioning post is greater than the height of the material placement platform.

[0008] Multiple sprockets can be positioned by controlling multiple clamping assemblies through an overall start switch. By defining the movement path of the chamfering tool through the machining center program, multiple locating pin holes on the sprockets can be chamfered simultaneously. Using this technical solution, multiple workstations on the tooling base plate can position and place multiple sprockets at once, effectively improving the efficiency of sprocket changing. The clamping assemblies can apply clamping force to the sprockets from different directions, fixing them to the placement table and reducing sprocket displacement and loosening.

[0009] First, align the center mounting holes of multiple sprockets with the positioning pins and place them on multiple material platforms. Then, clamp and fix the sprockets simultaneously from different directions using multiple clamping components. Next, the chamfering cutter chamfers the multiple positioning pin holes of the sprockets in sequence according to the movement path, which can reduce the time of rotating the sprockets. Then, chamfer the other sprockets in sequence, which effectively improves the processing efficiency of sprocket chamfering.

[0010] Optionally, a groove is provided on the end face of the material placement platform, and the positioning post is perpendicular to the bottom of the groove.

[0011] By adopting the above technical solution, the chips generated during the chamfering process of the sprocket will fall onto the surface of the material placement table. The groove can collect the chips, making it easy to clean them manually. It also helps to reduce the accumulation of chips on the material placement table and reduce the impact on the positioning accuracy of the sprocket chamfer.

[0012] Optionally, the material placement platform has multiple notches along its circumference, and the multiple notches are connected to the groove. After the sprocket is chamfered, the sprocket can be easily picked up through the notches, and the chips in the groove can also be easily blown away from the notches.

[0013] By adopting the above technical solution, the notch and the groove are connected to form a chip removal channel, which can blow chips away from the material placement table through the notch, reducing chip accumulation in the groove. The notch provides space to contact the edge of the sprocket, allowing fingers or other tools to pick up the sprocket through the notch, facilitating material changing or retrieval.

[0014] Optionally, the material placement platform and the positioning column are detachably connected.

[0015] By adopting the above technical solution, the positioning column and the material placement platform are detachably connected, making it convenient to replace the positioning column to adapt to different specifications of sprockets and improving the adaptability of the positioning column.

[0016] Optionally, a support column is provided on the material placement platform. The support column is arranged parallel to the positioning column, and the support column is used to pass through the weight reduction hole of the sprocket.

[0017] By adopting the above technical solution, the support column can circumferentially position the sprocket, reduce the displacement of the sprocket, and effectively improve the stability of the sprocket fixed on the material placement platform.

[0018] Optionally, an elastic element is sleeved on the support column, one end of the elastic element abuts against the bottom of the groove, and the end of the elastic element away from the groove abuts against the sprocket.

[0019] By adopting the above technical solution, when the sprocket is fitted onto the positioning post and support post, the elastic element contracts and generates elastic force under the weight of the sprocket. After the sprocket chamfering is completed, the clamping assembly is controlled to loosen the sprocket, and the sprocket is lifted up under the elastic force of the elastic element, making it easy for the sprocket to be picked up manually.

[0020] Optionally, the clamping assembly includes a driving component and a clamping plate. The driving component is fixedly mounted on the tooling base plate, one end of the clamping plate is fixedly mounted to the output shaft of the driving component, and the other end of the clamping plate is located at the top of the material placement platform.

[0021] By adopting the above technical solution, the telescopic motion of the drive component is converted into a vertical clamping force of the clamping plate on the sprocket, which can clamp the circumferential edge area of ​​the sprocket, reduce the vibration or slippage of the sprocket, and improve the stability of the sprocket fixed on the material placement table.

[0022] Optionally, the bottom of the material placement platform is provided with a base, and the base is provided with a locking component to fix the base to the tooling base plate.

[0023] By adopting the above technical solution, the base and the tooling base plate are detachably connected, which facilitates the replacement or repair of the material placement platform and reduces maintenance costs.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By controlling multiple clamping components through the overall start switch, the unified clamping and release of multiple sprockets is realized. Combined with the chamfering tool movement path defined by the machining center program, the chamfering of multiple positioning pin holes of the sprocket can be completed in one go, realizing the batch replacement and renewal of sprockets, significantly increasing the number of sprockets processed per shift, thereby effectively improving the processing efficiency of sprockets.

[0026] 2. By opening grooves and multiple notches on the material placement platform, the grooves and notches cooperate to form a chip removal channel, which not only reserves space for chip blowing, but also makes it convenient to manually remove the sprocket;

[0027] 3. By fixing a support column with a weight-reducing hole for the sprocket on the material placement platform, the sprocket can be circumferentially positioned, reducing sprocket displacement and effectively improving the stability of the sprocket fixed on the material placement platform.

[0032] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0033] This application discloses a quick-change tooling for accelerating chamfering, referring to... Figure 1 and Figure 2 The system includes a rectangular base plate 1 with eight workstations fixed on it. These workstations are divided into two groups: four workstations process the front chamfer of the sprockets, and the other four workstations process the back chamfer of the sprockets. Each workstation group has a loading platform 2 and two clamping components 3 fixed on it, located on opposite sides of the loading platform 2. A positioning pin 4 is threaded onto the top center of the loading platform 2, with the height of the positioning pin 4 exceeding the height of the loading platform 2. Multiple sprockets are first placed on the loading platform 2. Then, a pneumatic switch controls the multiple clamping components 3 to achieve unified positioning of the sprockets. Following the defined path of the chamfering cutter programmed by the machining center, the chamfering cutter performs front and back chamfering on the multiple positioning pin holes of the sprockets, reducing the sprocket rotation time. This process is then repeated for other sprockets, effectively improving the chamfering efficiency of the sprockets.

[0034] Reference Figure 2 The clamping assembly 3 includes a driving component 31 and a clamping plate 32. In this embodiment, the driving component 31 is a cylinder. The bottom of the cylinder is fixed to the tooling base plate 1 by bolts, and one end of the clamping plate 32 is vertically fixed to the output shaft of the cylinder by bolts. The other end of the clamping plate 32 is located at the top of the material placement platform 2. Multiple cylinders are controlled by an air circuit switch, so that the two clamping plates 32 are uniformly positioned at the circumferential edge of the sprocket. This facilitates the chamfering cutter to chamfer multiple sprockets simultaneously, effectively improving the efficiency and stability of sprocket processing. The centers of the two clamping plates 32 and the positioning post 4 are located on the same horizontal line, which can form a balanced clamping force on the sprocket, reducing the deformation of the sprocket caused by the concentration of clamping force, and further improving the chamfering accuracy and stability of the sprocket.

[0035] Reference Figure 1The top of the material placement platform 2 has a groove 5, which is ring-shaped. The positioning post 4 is vertically fixed to the bottom of the groove 5. The groove 5 can collect the chips generated by the sprocket processing, which is convenient for manual cleaning. The material placement platform 2 has four notches 6 evenly distributed around its circumference. The portion of the material placement platform 2 between adjacent notches 6 forms a protrusion 11 for supporting the sprocket. The notches 6 are interconnected with the groove 5, which facilitates blowing away the chips in the groove 5 through the notches 6, and also facilitates the removal of the sprocket from the notches 6 for material replacement and retrieval.

[0036] Reference Figure 1 The bottom of the material placement platform 2 is integrally formed with a base 9. Four locking elements 10 are threaded at the four corners of the end face of the base 9. In this embodiment, the locking elements 10 are bolts. The base 9 is threadedly fixed to the tooling base plate 1 by bolts, which facilitates the disassembly and replacement of the base 9 and the material placement platform 2, and reduces maintenance costs.

[0037] Reference Figure 3 A support column 7 is fixed on the material placement platform 2. The support column 7 is perpendicular to the bottom of the groove 5. The support column 7 is used to pass through the weight reduction hole on the sprocket and to position the sprocket circumferentially, which can reduce the lateral displacement of the sprocket and improve the stability of the sprocket. An elastic element 8 is sleeved on the support column 7. In this embodiment, the elastic element 8 is a compression spring. The height of the compression spring is greater than the height of the protrusion 11 on the material placement platform 2. When the compression spring contracts under the weight of the sprocket, the compression spring generates elastic force, which can lift the chamfered sprocket, making it easier to pick up the material.

[0038] The implementation principle of the quick-change tooling for chamfering speed disclosed in this application embodiment is as follows: First, multiple sprockets are placed on the material placement table 2, wherein the positioning pin 4 passes through the central mounting hole of the sprocket, and the support pin 7 passes through the weight reduction hole of the sprocket. Then, multiple cylinders are controlled by the overall start switch, so that the clamping plate 32 fixes the circumferential edge of the sprocket, effectively improving the positioning accuracy of the sprocket. The tooling base plate 1, through reasonable structural design, utilizes the front chamfering processing group and the back chamfering processing group, and then defines the movement path of the chamfering tool through the machining center, simultaneously chamfering different surfaces of multiple positioning pin holes of the sprocket, reducing the time for manual rotation of the sprocket. Then, other sprockets are chamfered in sequence, realizing batch replacement and renewal of sprockets, effectively improving the processing efficiency and stability of the sprockets.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
