Description

Technical Field

[0001] This utility model relates to the field of beveling machine technology, and more specifically, to a beveling machine with a quick-release tool structure. Background Technology

[0002] There are two common methods for beveling: mechanical cutting and thermal cutting. Mechanical cutting is commonly used for beveling, employing various types of general-purpose machine tools such as beveling machines, edge planers, milling machines, planers, and lathes. This method produces bevels with precise dimensions and good surface quality.

[0003] A search revealed that patent publication number CN212793027U discloses a small-diameter pipe beveling machine, which has a base. A drive device is horizontally fixed at one end of the base. The drive device is fixed to both sides by a front chuck and a rear chuck, respectively, with a workpiece clamped between them. A beveling assembly is mounted on the other side of the drive device on the base. The beveling assembly includes a guide rail, a movable tool holder, a beveling machine main unit, and cutting tools. This small-diameter pipe beveling machine adds a water-cooling system for the cutting head, which is absent in ordinary beveling machines, making the cutting head more durable. It features a reasonable structure, simple operation, flexibility, reliability, high stability, economic practicality, small size, light weight, and strong environmental adaptability. It can process beveling of different lengths for carbon steel pipes and stainless steel pipes with diameters below 114 mm and thicknesses less than 30 mm. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing beveling machines have relatively durable cutting tools, but wear is inevitable during long-term cutting. As the cutting edge wears, the processing quality of the beveling will decrease, such as increased surface roughness and larger deviation of the beveling angle. When the wear reaches a certain level, the cutting tool needs to be replaced in time to ensure processing accuracy. In the process of mass production, different types of workpieces often need to be processed. Time is money, and the cutting tool needs to be replaced frequently. However, the replacement time is too long, which greatly reduces the working efficiency of the beveling machine.

[0005] Therefore, a beveling machine with a quick-release tool structure is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a beveling machine with a quick-release tool structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a beveling machine with a quick-release tool structure, comprising a beveling machine body, a lifting platform, a primary clamping block and a secondary clamping block, wherein the front end face of the beveling machine body is provided with a clamping jaw, the left side of the beveling machine body is provided with a control box, the bottom of the front end face of the beveling machine body is provided with a base, and electric telescopic columns are provided at the four corners of the upper end of the base, the lifting platform is provided on the upper end face of the four sets of electric telescopic columns, and the upper end face of the lifting platform is provided with a sliding groove;

[0008] The primary clamping block is located on the left side of the inner cavity of the slide groove, and the secondary clamping block is located on the right side of the inner cavity of the slide groove. Fixing plates are installed on both sides of the slide groove. Cylinders are installed on the outer sides of both sets of fixing plates. Limiting grooves are formed at the front and rear of the upper end of the primary clamping block. A tool mounting seat is installed below the limiting groove. A limiting plate is installed on the upper left side of the secondary clamping block. A slot is formed at the lower end of the limiting plate. Bolts are installed at the upper and lower ends of one set of limiting plates. A support frame is located in front of the lifting platform. A conveyor seat is installed on the upper end of the support frame. Rollers are installed inside the conveyor seat. Three sets of rollers are arranged at equal intervals.

[0009] Preferably, the bottom surfaces of both the primary clamping block and the secondary clamping block abut against the inner cavity of the slide groove, and the primary clamping block and the secondary clamping block are mirror images of each other.

[0010] Preferably, the telescopic ends of the two sets of cylinders respectively pass through the two sets of fixing plates and the first-level clamping block and are connected to the second-level clamping block, and the first-level clamping block and the second-level clamping block form a clamping structure.

[0011] Preferably, the two sets of limiting grooves abut against the two sets of limiting plates respectively, and the tool mounting seat abuts against the slot.

[0012] Preferably, when the primary clamping block and the secondary clamping block move with the telescopic ends of the two sets of cylinders, they move linearly along the inner cavity of the slide groove.

[0013] Preferably, when the primary clamping block and the secondary clamping block approach each other via the cylinder, the two sets of limiting plates and the tool mounting seat are controlled to engage in the two sets of limiting grooves and slots to achieve fixation.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Compared with existing technologies, this beveling machine with a quick-release tool structure uses a locking design between a primary clamping block and a secondary clamping block. When a tool needs to be changed, the cylinder retracts, separating the primary and secondary clamping blocks, loosening the bolts, and thus releasing the locking between the tool mounting seat and the limiting plate. The tool can then be easily removed. By adopting this quick-release structure, due to its simple and automated operation, operators can quickly switch between different tools without waiting, making the tool change process faster.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As attached Figures 1 to 4The beveling machine shown includes a beveling machine body 1, a lifting platform 6, a primary clamping block 10 and a secondary clamping block 11. The front end face of the beveling machine body 1 is provided with a clamping jaw 2. The left side of the beveling machine body 1 is provided with a control box 3. The bottom of the front end face of the beveling machine body 1 is provided with a base 4. Electric telescopic columns 5 are provided at the four corners of the upper end of the base 4. The lifting platform 6 is located on the upper end face of the four sets of electric telescopic columns 5. The upper end face of the lifting platform 6 is provided with a sliding groove 7.

[0024] The primary clamping block 10 is located on the left side of the inner cavity of the slide 7, and the secondary clamping block 11 is located on the right side of the inner cavity of the slide 7. Fixing plates 8 are installed on both sides of the slide 7, and cylinders 9 are installed on the outer sides of both sets of fixing plates 8. Limiting grooves 101 are opened at the front and rear of the upper end of the primary clamping block 10, and a tool mounting seat 102 is installed below the limiting groove 101. A limiting plate 111 is installed on the upper left side of the secondary clamping block 11, and a slot 112 is opened at the lower end of the limiting plate 111. Bolts 113 are installed at the upper and lower ends of one set of limiting plates 111. A support frame 12 is set in front of the lifting platform 6, and a conveyor seat 13 is installed on the upper end of the support frame 12. Rollers 14 are installed in the inner cavity of the conveyor seat 13. There are three sets of rollers 14, and the three sets of rollers 14 are arranged at equal intervals.

[0025] Among them: When starting work, the caliper jaw 2 can accurately position and clamp the workpiece to be processed. When processing round pipes or square pipe fittings, the caliper jaw 2 can firmly clamp the workpiece by adjusting the opening degree of the caliper jaw 2. It can adapt to workpieces of different diameters and shapes, keeping them stable during beveling. The control box 3 can conveniently set various parameters on the box. The electric telescopic columns 5 at the four corners of the upper end of the base 4 can adjust the height of the tool through the lifting platform 6, so that the tool can accurately align with the pipe body at the caliper jaw 2 for processing. The slide groove 7 provides precise guidance for the movement of the primary clamping block 10 and the secondary clamping block 11. The fixing plate 8 fixes the position of the cylinder 9, so that the primary clamping block 10 and the secondary clamping block 11 can stably move linearly along the slide groove 7 under the drive of the cylinder 9. Positioned above the tool mounting base 102, the limiting groove 101 and the tool mounting base 102 abut against the slot 112 and the limiting plate 111 at the secondary clamping block 11, thereby clamping a standard-sized tool. The rotation of the bolt 113 abuts against the tool surface, thus preventing deviation during cutting. When disassembly is required, the telescopic end of the cylinder 9 retracts, separating the primary clamping block 10 and the secondary clamping block 11, and loosening the bolt 113, thereby releasing the clamping of the tool. The tool can be easily and quickly removed. The support frame 12 provides a stable support platform for the transfer base 13. The transfer base 13 and its three sets of rollers 14 in the inner cavity form a simple workpiece transfer device, which facilitates the loading and unloading of workpieces. During the processing, the rolling of the rollers 14 makes it easy to remove the workpiece after processing.

[0026] Example 2

[0027] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0028] In a preferred embodiment, the bottom surfaces of the primary clamping block 10 and the secondary clamping block 11 abut against the inner cavity of the slide groove 7, and the primary clamping block 10 and the secondary clamping block 11 correspond to each other in a mirror manner; furthermore, by corresponding to and abutting against the inner cavity of the slide groove 7 in a mirror manner, the slide groove 7 provides precise guidance for the primary clamping block 10 and the secondary clamping block 11.

[0029] In a preferred embodiment, the telescopic ends of the two sets of cylinders 9 respectively pass through the two sets of fixing plates 8 and the first-level clamping block 10 and are connected to the second-level clamping block 11, and the first-level clamping block 10 and the second-level clamping block 11 form a clamping structure; further.

[0030] In a preferred embodiment, the two sets of limiting grooves 101 abut against the two sets of limiting plates 111 respectively, and the tool mounting seat 102 abuts against the slot 112. Furthermore, the two sets of cylinders 9 are respectively connected to the primary clamping block 10 and the secondary clamping block 11, which can provide a balanced and stable clamping force for the clamping structure. During the processing, the tool will be subjected to the reaction force from the workpiece. The stable clamping force of the cylinder 9 can ensure that the tool is firmly fixed in the appropriate position and prevent it from being displaced due to external force.

[0031] In a preferred embodiment, the primary clamping block 10 and the secondary clamping block 11 move linearly along the inner cavity of the slide groove 7 as the telescopic ends of the two sets of cylinders 9 move. Furthermore, when the cylinder 9 is driven, the primary clamping block 10 and the secondary clamping block 11 can only move along the linear path specified by the slide groove 7. This precise guiding effect allows the primary clamping block 10 and the secondary clamping block 11 to accurately align the limiting groove 101 and the tool mounting seat 102 with the limiting plate 111 and the slot 112 respectively as they approach or move away. This allows the tool to be easily placed in the appropriate position. Then, the cylinder 9 is retracted to tightly clamp the tool, ensuring that the tool is securely installed.

[0032] In a preferred embodiment, when the primary clamping block 10 and the secondary clamping block 11 approach each other via the cylinder 9, the two sets of limiting plates 111 and the tool mounting base 102 are locked into the two sets of limiting grooves 101 and slots 112 for fixation. Furthermore, when the limiting plate 111 is locked into the limiting groove 101 and the tool mounting base 102 is locked into the slot 112, the tool is precisely positioned from multiple dimensions. Through this locking and fixing method, the tool is firmly restricted to the set position. The various locking parts work together to bear and disperse these external forces, so that the tool can remain stable during operation. The operator only needs to control the extension and retraction of the cylinder 9 to achieve the approach and separation of the primary clamping block 10 and the secondary clamping block 11, and loosen the bolt 113 appropriately to easily complete the locking and unlocking operation of the tool.

[0033] The working process of this utility model is as follows: First, when the beveling machine starts working, the workpiece to be processed is placed in the caliper jaw 2. The workpiece is firmly clamped by the adjustment mechanism of the caliper jaw 2, and the caliper in the caliper jaw 2 is rotated by the beveling machine body 1, thereby driving the workpiece to rotate. Then, the operator sets the corresponding parameters on the control box 3 according to the processing requirements. When it is necessary to install the tool, the control system drives the two sets of cylinders 9 to extend, so that the first-level clamping block 10 and the second-level clamping block 11 move in opposite directions along the slide 7, increasing the distance between them. The appropriate tool is placed on the tool mounting seat 102 on the first-level clamping block 10. Then, the control system causes the cylinder 9 on the fixing plate 8 to retract, and the first-level clamping block 10 and the second-level clamping block 11 move closer to each other.

[0034] During the approach process, the limiting groove 101 at the upper end of the primary clamping block 10 and the limiting plate 111 on the left side of the secondary clamping block 11 precisely align and abut against each other. At the same time, the tool mounting seat 102 accurately engages in the slot 112 at the lower end of the secondary clamping block 11, thus firmly fixing the tool. The bolts 113 installed at the upper and lower ends of one set of limiting plates 111 can further enhance the stability of the connection and prevent the tool from accidentally loosening or shifting during processing. Then, the height of the lifting platform 6 is adjusted by the electric telescopic columns 5 at the four corners of the upper end of the base 4. The electric telescopic columns 5 receive external command signals through the internal control system. The control system controls the rotation direction and speed of the motor in the electric telescopic columns 5 according to these commands, thereby realizing the rise or fall of the telescopic columns. It can also receive locking signals to fix the height. The four sets of electric telescopic columns 5 adjust their own lifting height at the same time, so that the installed tool is aligned with the position on the workpiece where the bevel needs to be processed.

[0035] During the processing, the cutting tool rotates at high speed under the drive of the beveling machine body 1. At the same time, the electric telescopic column 5 can drive the lifting table 6 and the cutting tool to gradually approach the workpiece according to the set feed speed, and perform beveling cutting on the workpiece. After a batch of workpieces is processed, if it is necessary to change the cutting tool to process the next batch of workpieces with different requirements, the control system drives the cylinder 9 to extend again, so that the first-level clamping block 10 and the second-level clamping block 11 are separated. By appropriately loosening the distance of the bolt 113, the old cutting tool can be easily removed. Repeat the above cutting tool installation steps to replace the new cutting tool. The support frame 12 fixes the conveyor seat 13. The three sets of rollers 14 arranged at equal intervals in its inner cavity can be used to assist the unloading operation of the workpiece. The above is the working principle of a beveling machine with a quick-release cutting tool structure.
