Description

Technical Field

[0001] This invention relates to the field of idler roller stop processing technology, and in particular to an idler roller stop processing machine tool. Background Technology

[0002] As a key component of belt conveyors, idler rollers bear the important responsibility of supporting the conveyor belt and the weight of the materials it carries. According to the manufacturing process requirements of idler rollers, the steel pipes need to undergo finishing processes such as chamfering, internal and external beveling, and end-face processing. Currently, there are two main processing modes for the finishing of idler roller steel pipes in these stages: The first mode involves completing the external beveling operation simultaneously with the cutting of the steel pipe. After completing the external beveling, the internal beveling and the end face of the steel pipe require secondary processing using a general-purpose lathe. However, in actual production, quality control mainly relies on manual sampling. On the one hand, manual sampling requires a large workforce, lengthening the production cycle and significantly increasing labor costs. On the other hand, the limitations of manual operation result in extremely low inspection efficiency, low accuracy of inspection results, and difficulty in maintaining stable product quality. Consequently, after the steel pipe is installed in bearing housings, bearings, and sealing components, key indicators such as radial runout, rotational resistance, and axial movement are difficult to guarantee effectively. Summary of the Invention

Detailed Implementation

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] like Figure 1 , Figures 4 to 6As shown, this invention provides a machine tool for machining idler roller stops, including a bed 1, a first detection device 2, a second detection device 3, a feed device 4, and a spindle rotary clamping device 5. The bed 1 is used to install and fix all other components, ensuring the rigidity and stability of the machine tool. Two spindle rotary clamping devices 5 are arranged opposite each other on both sides of the bed 1 to clamp the ends of the workpiece to be machined (such as an idler roller) and drive the workpiece to rotate for cutting. The spindle rotary clamping devices 5 are slidably mounted on the bed 1 to reciprocate along a first direction, allowing them to adapt to workpieces of different lengths and improving the machine tool's versatility. Two feed devices 4 are slidably mounted on one side of the corresponding spindle rotary clamping device 5 to... The spindle rotation clamping device 5 moves to complete the cutting of the workpiece stop. The first detection device 2 includes a first diameter sensor 21 and a second diameter sensor 22. The first diameter sensor 21 is installed inside the tool end of the feed device 4, and the second diameter sensor 22 is installed on the side of the feed device 4 away from the tool end. It is used to measure the diameter of the workpiece after machining. The second detection device 3 includes a first distance sensor 31 and a second distance sensor 32. The first distance sensor 31 is installed inside the tool end of the feed device 4, and the second distance sensor 32 is installed on the side of the feed device 4 facing the bed 1. It is used to measure the distance after machining, which is the distance between the two stops of the idler roller.

[0034] Based on the above structure, during the machining stage, the feed device 4 drives the tool tip to feed towards the workpiece for stop cutting. At this time, the two spindle rotary clamping devices 5 clamp the workpiece and rotate to realize the turning action. After machining is completed, the feed device 4 continues to move slowly, preparing to enter the measurement state. During the movement of the feed device 4, the second diameter sensor 22 senses the moving distance of the feed device 4 to acquire data on large stroke displacement. When the feed device 4 continues to move forward, and the first diameter sensor 21 just contacts the workpiece surface, a signal change is generated. At this moment, the movement of the feed device 4 is immediately stopped, and the data of the first diameter sensor 21 and the second diameter sensor 22 are recorded. Using the readings of the first diameter sensor 21 and the second diameter sensor 22, combined with the movement of the feed device 4, the actual outer diameter of the workpiece after machining is calculated. Similarly, the distance between the two stops is calculated using the collaborative work of the first distance sensor 31 and the second distance sensor 32.

[0035] This embodiment utilizes the second diameter sensor 22 (second pitch sensor 32) for long-stroke positioning, and then the first diameter sensor 21 (first pitch sensor 31) captures the detection value at the moment of contact, thereby realizing the measurement of the workpiece size. Compared with manual spot checks, it not only improves the measurement accuracy, but also improves the detection efficiency and reduces labor costs.

[0036] The first direction in this embodiment is along the axial direction of the idler roller.

[0037] like Figure 2 and Figure 6 As shown, the feed device 4 includes a first slide assembly 41, a second slide assembly 42, a bracket 43, and a cutting tool 44. The first slide assembly 41 is slidably mounted on the spindle rotary clamping device 5 to reciprocate along a first direction, thereby realizing the positioning movement of the cutting tool 44 in the length direction of the workpiece, used to adjust the machining position (such as the position of the cutting stop) or to perform axial cutting feed. The second slide assembly 42 is slidably mounted on the first slide assembly 41 to reciprocate along a second direction. The first direction and the second direction are set perpendicularly, and the second direction is the radial direction of the support roller, so as to realize the radial feed movement of the cutting tool 44, that is, to control the cutting depth of the cutting tool 44 into the workpiece. The bracket 43 is mounted on the second slide to provide a rigid connection to ensure the stability of the cutting tool 44 during the cutting process. The cutting tool 44 is mounted on the side of the bracket 43 facing the support roller. The first diameter sensor 21 is mounted on the side of the cutting tool 44 facing the inner wall of the support roller. During the measurement stage, when the feed device 4 slowly advances, the first diameter sensor 21 will first contact the workpiece surface, and after capturing the contact moment signal, the feed will stop immediately. The first pitch sensor 31 is installed inside one side of the stop of the idler roller. That is, the first pitch sensor 31 is installed inside the cutter end and faces the stop surface. During the feeding process, it senses the position of the stop boundary to measure the pitch between the two stops. The second diameter sensor 22 is installed on the side of the second slide assembly 42 away from the cutter 44 to record the overall radial movement stroke of the second slide assembly 42.

[0038] In this embodiment, the feed device 4 adopts a two-stage slide structure and multiple integrated sensors to construct a composite machining device with dual-axis motion and detection functions. It can not only complete the cutting task, but also measure the size of the workpiece after machining.

[0039] like Figure 4 and Figure 9 As shown, the first slide assembly 41 includes a first slide plate 411, a first slider, a first slide rail 412, and a first drive member. The first slide rail 412 is mounted on the spindle rotary clamping device 5. The first slide plate 411 is slidably mounted on the first slide rail 412 via the first slider. The first drive member is connected to the first slider. The second slide assembly 42 is mounted on the first slide plate 411. In this embodiment, the first drive member drives the first slider to move along the length direction of the first slide rail 412, thereby moving the second slide assembly 42 and achieving position adjustment in the axial direction. In this embodiment, the first drive member is a cylinder.

[0040] Furthermore, the second slide assembly 42 includes a second slide plate 421, a second slider, a second slide rail, and a second drive component. The second slide rail is mounted on the first slide plate 411, and the second slide plate 421 is slidably mounted on the second slide rail via the second slider. The second drive component is connected to the second slider, and the bracket 43 is mounted on the second slide plate 421. In this embodiment, the movement of the first slide plate will drive the second slide plate to move as a whole. The second drive component drives the second slider to slide along the length direction of the second slide rail, thereby moving the bracket 43 and achieving position adjustment in the radial direction. In this embodiment, the second drive component is a cylinder.

[0041] Furthermore, the first detection device 2 also includes a first magnetic scale 23 and a first connecting frame 24. The first magnetic scale 23 is installed on the side of the first slide plate 411 away from the cutter 44 and is used to measure the displacement of the first slide assembly 41 in the second direction in real time. The first connecting frame 24 is connected to the second slide plate 421, and the second diameter sensor 22 is correspondingly set with the first magnetic scale 23 through the first connecting frame 24.

[0042] In this embodiment, the first slide moves the entire feed device 4 to the stop position, and the movement data is acquired in real time through the cooperation of the second diameter sensor 22 and the first magnetic scale 23. Then, the second slide continues to feed slowly until the first diameter sensor 21 contacts the workpiece surface, at which point the data of the first diameter sensor 21 is recorded. At the same time, the second diameter sensor 22 records the total feed amount, and the system calculates the actual diameter by combining the data from the two sensors; the stop detection at the other end repeats the above process.

[0043] like Figure 10 As shown, the second detection device 3 also includes a second magnetic scale 33 and a second connecting frame 34. The second magnetic scale 33 is installed on the bed 1, the second connecting frame 34 is connected to the first slide plate 411, and the second distance sensor 32 is correspondingly set with the second magnetic scale 33 through the second connecting frame 34. When the first slide table drives the second connecting frame 34 and the second distance sensor 32 to move, their position change can be accurately measured by the relative movement between the second magnetic scale 33 and its reading head.

[0044] In this embodiment, the first slide moves the feed device 4 to the stop position, and the movement data is acquired in real time through the cooperation of the second distance sensor 32 and the second magnetic scale 33. The feed device 4 at the other end performs the above steps at the same time, and then continues to feed slowly with the cooperation of the second slide until the first distance sensor 31 contacts the workpiece surface. At this time, the data of the first distance sensor 31 is recorded, and the system calculates the actual distance by combining the data of the two sensors.

[0045] like Figures 2 to 5As shown, the spindle rotation clamping device 5 includes a spindle rotation clamp 51, a third drive member 52, a synchronous belt, a third slide plate 53, a third slider, a third slide rail 54, and a fourth drive member. The third slide rail 54 is mounted on the bed 1, and the third slide plate 53 is slidably mounted on the third slide rail 54 via the third slider. The fourth drive member is connected to the third slider. The spindle rotation clamp 51 and the third drive member 52 are mounted on the third slide plate 53, and the spindle rotation clamp 51 and the third drive member 52 are connected by a synchronous belt drive.

[0046] Based on the above structure, the third drive unit 52 in this embodiment is activated, driving the spindle rotary chuck 51 to rotate via synchronous belt transmission, thereby achieving high-speed rotary machining of the workpiece. The fourth drive unit drives the third slider to move along the length of the third slide rail 54, thereby moving the third slide plate 53 assembly and achieving axial position adjustment. In this embodiment, the third drive unit 52 is a motor, and the fourth drive unit is a cylinder.

[0047] It should be noted that the spindle rotary clamp 51 in this embodiment is a conventional spindle rotary clamp 51, and its structure is not specifically limited here.

[0048] like Figure 7 As shown, it also includes an auxiliary clamping device 6, which is disposed between the two spindle rotary clamping devices 5. The auxiliary clamping device 6 includes a first mounting frame 61, a clamping jaw 62, and a fifth driving member. The first mounting frame 61 is mounted on the bed 1, the fifth driving member is mounted on the first mounting frame 61, and the fifth driving member is connected to the clamping jaw 62 to drive the clamping jaw 62 to clamp or release.

[0049] Based on the above structure, when the workpiece is clamped from both ends by the two spindle rotary clamping devices 5, the fifth drive unit actuates, pushing or pulling the clamping jaws 62 to open, thus avoiding interference with the workpiece machining. After machining is completed, the fifth drive unit reverses its action, closing the clamping jaws 62 to fix the workpiece and prevent it from moving.

[0050] like Figure 8 As shown, it also includes a tool damage detection device 7, which includes a second mounting bracket 71 and a tool detection unit 72. The second mounting bracket 71 is mounted on the bed 1 to ensure that the tool detection unit 72 itself is stable and will not be affected by vibration or movement. The tool detection unit 72 is mounted on the side of the second mounting bracket 71 facing the tool end, so that it can accurately observe or sense the state of the tool 44 to detect whether the tool 44 is damaged.

[0051] This embodiment, by incorporating a tool damage detection device 7, prevents the processed workpiece from becoming defective due to tool breakage, thus avoiding batch scrapping. Simultaneously, it prevents a broken tool 44 from flying out during high-speed rotation, causing equipment damage or even personal injury. The tool detection unit 72 in this embodiment can be a vision sensor, laser scanner, contact probe, acoustic emission sensor, or current monitoring module, etc.

[0052] Furthermore, the plane containing the third slide plate 53 is inclined relative to the vertical plane. Understandably, this inclination is achieved by setting a corresponding angle of inclination on the bed 1 itself, preferably 45°. By setting the inclination, iron and aluminum chips generated during cutting can slide directly into the chip conveyor at the bottom of the machine tool under their own weight, eliminating the need for the chain-plate chip conveyor required by the flat bed 1. This saves costs and avoids downtime caused by chip jamming or malfunction of the chip conveyor. In addition, chips do not accumulate in the machining area and on the guide rail surface, reducing scratches on the machined surface of the workpiece and preventing wear or decreased accuracy caused by chips entering the guide rail gaps.

[0053] In practical applications, the inclined plane setting can make the spindle center and the guide rail surface form a reasonable angle, reducing the long-term impact of guide rail wear on machining accuracy. Compared with the traditional flat bed, the inclined plane layout is more compact and can integrate more functions (such as turret and tailstock) in a smaller footprint, making it suitable for workshop-intensive production.

[0054] In summary, the present invention provides a roller stop processing machine tool, which uses a second diameter sensor 22 (second pitch sensor 32) for large stroke positioning, and then uses a first diameter sensor 21 (first pitch sensor 31) to capture the detection value at the moment of contact, thereby realizing the size measurement of the workpiece. Compared with manual inspection, it not only improves the measurement accuracy, but also improves the inspection efficiency and reduces labor costs.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
