Description

Technical Field

[0001] This utility model belongs to the technical field of cutter heads for beveling machines, specifically relating to an upper and lower combined cutter head for beveling machines. Background Technology

[0002] Beveling is a crucial pretreatment process before welding, and its quality directly affects the strength, sealing performance, and service life of the subsequent welded joint. The beveling machine cutter head, as the core component for beveling, plays a decisive role in processing efficiency, accuracy, and cost control through its performance and structural design. As industrial manufacturing develops towards higher precision, greater variety, and greater flexibility, traditional beveling machine cutter heads are gradually revealing numerous problems that fail to meet actual production needs.

[0003] Currently, the industrial sector has increasingly diverse requirements for workpiece beveling angles. For example, in pipe welding, 30-degree or 35-degree V-grooves are often required to ensure weld penetration and joint strength. In pressure vessel manufacturing, 45-degree beveling is commonly used for thick-walled plates to reduce the number of welding layers and improve welding efficiency. In the processing of irregularly shaped parts under special working conditions, non-standard beveling angles between 30 and 45 degrees are also required. However, traditional beveling machine cutter heads generally adopt an integrated structural design, and their clamping angle is fixed during the manufacturing stage, making it impossible to adjust according to the processing requirements of different workpieces. Therefore, those skilled in the art have provided a beveling machine with an upper and lower combined cutter head to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a simple and reasonably designed upper and lower combined cutter disc for a beveling machine in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A beveling machine with upper and lower combined cutter heads, the upper and lower combined cutter heads including an upper cutter head with independently changeable clamping angle, a lower cutter head with independently changeable clamping angle, and a cutter head intermediate connecting member for connecting the upper cutter head and the lower cutter head, wherein the upper cutter head and the cutter head intermediate connecting member are detachably connected, and the lower cutter head and the cutter head intermediate connecting member are detachably connected.

[0006] As a further optimization of this utility model, positioning holes are provided at the bottom of the upper cutter disc and the top of the lower cutter disc. The two positioning holes are symmetrically distributed, and pin holes are provided on the side walls of the two positioning holes in a polar day array. The inner side walls of the two sets of pin holes are jointly inserted with cutter disc pins. The cutter disc pins are used to achieve circumferential fixation of the upper cutter disc, the lower cutter disc and the intermediate connecting piece of the cutter disc.

[0007] As a further optimization of this utility model, the clamping angle of the upper cutter head can be selected according to the requirements of the workpiece being processed, and the selectable clamping angle includes, but is not limited to, 30 degrees and 45 degrees. The clamping angle of the lower cutter head can also be selected according to the requirements of the workpiece being processed, and the selectable clamping angle includes, but is not limited to, 30 degrees and 45 degrees.

[0008] As a further optimization of this utility model, the side wall of the intermediate connecting member of the cutter disc is provided with a positioning groove, the lower end face of the upper cutter disc is embedded in the positioning groove at the upper end of the intermediate connecting member of the cutter disc, and the upper end face of the lower cutter disc is embedded in the positioning groove at the lower end of the intermediate connecting member of the cutter disc. The depth of the positioning groove is adapted to the thickness of the upper and lower cutter discs to ensure the circumferential positioning accuracy of the upper and lower cutter discs.

[0009] As a further optimization of this utility model, the upper cutter head has an upper cutter head mounting hole at the top, and the lower cutter head has a lower cutter head mounting hole at the bottom. The upper cutter head mounting hole connects the upper cutter head to the power output end of the beveling machine through fixing bolts, and the lower cutter head mounting hole connects the lower cutter head to the fixed base of the beveling machine through fixing bolts.

[0010] As a further optimization of this utility model, the number of pin holes in each group is at least one and they are symmetrically distributed along the circumferential direction of the intermediate connecting member of the cutter head, the upper cutter head and the lower cutter head. Each pin hole is equipped with a corresponding cutter head pin to improve the circumferential stability of the upper cutter head, the lower cutter head and the intermediate connecting member of the cutter head.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model completely solves the problem of fixed angles by splitting the cutter head into an upper cutter head and a lower cutter head with independently changeable clamping angles, and using a middle connecting piece of the cutter head to achieve detachable connection. The clamping angles of the upper and lower cutter heads can be flexibly selected according to processing requirements. The selectable range includes, but is not limited to, 30 degrees and 45 degrees. Other angles can also be customized according to special requirements. It can realize conventional combinations such as "both upper and lower are 45 degrees", "upper 45 degrees and lower 30 degrees", "upper 30 degrees and lower 45 degrees", and can also adapt to non-standard beveling angle processing. This allows one beveling machine to cope with the processing needs of various workpieces, greatly expanding the applicable scenarios of the equipment. There is no need to purchase separate equipment for different beveling angles, which significantly improves processing flexibility and equipment utilization.

[0012] 2. In this utility model, positioning grooves are provided at both the upper and lower ends of the intermediate connecting part of the cutter head. Corresponding grooves are embedded in the lower end face of the upper cutter head and the upper end face of the lower cutter head, and the depth of the grooves is precisely matched with the thickness of the cutter head, which can strictly limit the circumferential rotation of the cutter head and ensure circumferential positioning accuracy. On the other hand, positioning holes are provided at the bottom of the upper cutter head and the top of the lower cutter head, and the number of positioning holes is at least 4 and symmetrically distributed along the circumference. A cutter head pin is installed in each positioning hole. With the connection of the upper cutter head mounting hole and the lower cutter head mounting hole through fixing bolts, the upper cutter head, the lower cutter head and the intermediate connecting part of the cutter head and the beveling machine are double fixed, which effectively avoids axial displacement and circumferential loosening.

[0013] 3. With this utility model, when replacing the cutter head, only the cutter head pin and fixing bolt need to be removed to remove the upper or lower cutter head separately. After replacing the cutter head with a new angle cutter head, the assembly can be completed by following the steps of aligning the positioning groove, inserting the cutter head pin, and tightening the fixing bolt. The whole process does not require complicated calibration, which improves the efficiency of installation and cutter head replacement. Attached Figure Description

[0016] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0017] Example 1: As Figure 1 , Figure 2 and Figure 4As shown, a beveling machine with upper and lower combined cutter heads includes an upper cutter head 1 with independently changeable clamping angles, a lower cutter head 2 with independently changeable clamping angles, and a cutter head intermediate connector 3 for connecting the upper cutter head 1 and the lower cutter head 2. The upper cutter head 1 and the cutter head intermediate connector 3 are detachably connected, and the lower cutter head 2 and the cutter head intermediate connector 3 are also detachably connected. By disassembling the upper cutter head 1 and the lower cutter head 2, they can be replaced with cutter heads with different clamping angles, thereby accurately adapting to the beveling angle requirements of the workpiece.

[0018] like Figure 1 , Figure 2 and Figure 4 As shown, positioning holes 5 are provided at the bottom of the upper cutter head 1 and the top of the lower cutter head 2, and the two positioning holes 5 are symmetrically distributed. The inner sidewalls of the two positioning holes 5 are jointly installed with cutter head pins 4. The cutter head pins 4 can effectively limit the relative displacement of the three in the axial direction and ensure the stability during the machining process. Furthermore, the sidewalls of the two positioning holes 5 are provided with pin holes 8 distributed in a polar pattern. The number of pin holes 8 in each group is at least 4, and they are symmetrically distributed along the circumferential direction of the cutter head intermediate connector 3, the upper cutter head 1, and the lower cutter head 2. Each pin hole 8 is equipped with a corresponding cutter head pin 4. Through the cooperation of the two groups of pin holes 8 and the cutter head pins 4, the circumferential stability of the upper cutter head 1, the lower cutter head 2 and the cutter head intermediate connector 3 is greatly improved, avoiding the impact of circumferential loosening on the beveling accuracy.

[0019] like Figure 1 - Figure 5 As shown, the clamping angle of the upper cutter head 1 can be flexibly selected according to the requirements of the workpiece being processed. The selectable clamping angles include, but are not limited to, 30 degrees and 45 degrees. Similarly, the clamping angle of the lower cutter head 2 can also be selected according to the requirements of the workpiece being processed. The selectable clamping angles also include, but are not limited to, 30 degrees and 45 degrees. In actual processing, the clamping angles of the upper cutter head 1 and the lower cutter head 2 can be flexibly combined according to the specific bevel requirements of the workpiece. For example, both the upper and lower cutter heads can be selected at 45 degrees, or the upper cutter head can be selected at 45 degrees and the lower cutter head at 30 degrees, or the upper cutter head can be selected at 30 degrees and the lower cutter head at 45 degrees. Other clamping angles can also be customized according to special processing requirements, which greatly expands the application range of this combination cutter head.

[0020] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a positioning groove 9 is provided on the side wall of the intermediate connecting member 3 of the cutter head. The lower end face of the upper cutter head 1 is embedded in the positioning groove 9 at the upper end of the intermediate connecting member 3 of the cutter head, and the upper end face of the lower cutter head 2 is embedded in the positioning groove 9 at the lower end of the intermediate connecting member 3 of the cutter head. The depth of the positioning groove 9 is adapted to the thickness of the upper cutter head 1 and the lower cutter head 2. This structural design can effectively limit the relative rotation of the upper cutter head 1 and the lower cutter head 2 in the circumferential direction, ensure the positioning accuracy of the cutter head during the processing, and thus ensure the quality of the beveling process.

[0021] It should be noted that, in the actual application of this beveling machine with its upper and lower combined cutter heads for beveling workpieces, the operator can first select the appropriate clamping angle of the upper cutter head 1 and the lower cutter head 2 according to the beveling angle requirements of the workpiece. Then, the lower end face of the upper cutter head 1 is inserted into the positioning groove at the upper end of the cutter head intermediate connector 3, and the upper end face of the lower cutter head 2 is inserted into the positioning groove 9 at the lower end of the cutter head intermediate connector 3, so that the upper cutter head 1, the lower cutter head 2, and the positioning holes 5 on the cutter head intermediate connector 3 correspond one-to-one. Finally, the cutter head pin 4 is installed into the positioning hole 5 to achieve axial and circumferential fixation of the three components. Finally, using the upper cutter head mounting hole 6 and the lower cutter head mounting hole 7, the upper cutter head 1 is connected and fixed to the power output end of the beveling machine, and the lower cutter head 2 is connected to the fixed base of the beveling machine, respectively, through the fixing bolts. This completes the installation of the combined cutter heads. After starting the beveling machine, the power output end drives the upper cutter head 1 to rotate, which cooperates with the fixed lower cutter head 2 to perform precise beveling on the workpiece. When it is necessary to process workpieces with different beveling angles, simply remove the lower cutter head pin 4 and the fixing bolts, replace the upper cutter head 1 or the lower cutter head 2 with the corresponding clamping angle, and then reassemble according to the above installation steps. The operation is simple and quick, and can effectively improve processing efficiency.

[0022] The above-described embodiments are merely examples of several implementations of this utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
