Description

Technical Field

[0001] This utility model relates to the field of processing equipment, and in particular to a large steel billet mirror surface processing machine tool. Background Technology

[0002] In modern industrial manufacturing, the mirror finish of large steel billets directly determines the quality and performance of downstream products. However, existing machine tools generally suffer from structural redundancy and large size. Traditional crossbeam components use a single-rail sliding design, resulting in excessively long crossbeams. This not only increases the equipment's footprint but also reduces processing stability due to center of gravity shift. Furthermore, existing equipment fails to effectively address the problem of multi-component displacement interference. Milling and grinding heads must frequently avoid each other during lateral movement, severely restricting processing efficiency and process continuity. In addition, there is a lack of real-time accuracy monitoring methods in the processing steps. Surface roughness detection relies on manual sampling or offline equipment, leading to unreliable processing accuracy and a high rework rate.

[0003] Therefore, how to develop a large steel billet mirror surface processing machine tool, reduce the length of the crossbeam body, enhance the structural compactness of the machine tool, and at the same time realize the real-time detection of the surface processing accuracy of the steel billet workpiece has become a technical problem that urgently needs to be solved by people in this field.

The square slider is threadedly connected to the first reciprocating screw.

[0010] Preferably, the crossbeam assembly further includes a second drive motor, a second reciprocating screw, a third drive motor, and a third reciprocating screw.

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] like Figure 1-6As shown, a large steel billet mirror surface processing machine tool includes a bed 1, a crossbeam assembly 2, a milling head 4, a rough grinding head 5, a fine grinding head 6, an ultra-fine grinding head 7, a workpiece slide plate 8, a downward pressure cylinder 9, and a laser surface roughness detector. The workpiece slide plate 8 is slidably connected to the top of the bed 1 via a first drive mechanism. A clamping fixture 3 for fixing the workpiece is installed on the workpiece slide plate 8. The clamping fixture 3 is equipped with a clamping cylinder and a floating cylinder. The crossbeam assembly 2 includes a crossbeam body 201, a sliding frame 208, a first slide plate 209, and a second slide plate 210. The crossbeam body 201 is horizontally mounted above the bed 1. The sliding frame 208 is slidably sleeved onto the crossbeam body 201. The first slide plate 209 and the second slide plate 210 are respectively mounted on the crossbeam body. The left and right sides of the body 201 are connected to the crossbeam body 201, and the first slide plate 209 and the second slide plate 210 are slidably connected to the crossbeam body 201. The left and right sides of the sliding frame 208 are respectively provided with first clearance holes for the first slide plate 209 and the second slide plate 210 to slide through. The milling head 4 and the fine grinding head 6 are slidably connected to the left and right sides of the sliding frame 208. The coarse grinding head 5 and the ultra-fine grinding head 7 are slidably connected to the first slide plate 209 and the second slide plate 210 respectively. The laser surface roughness detector is installed at the bottom of the sliding frame 208. Multiple pressing cylinders 9 are installed side by side below the crossbeam body 201, and the bottom of the sliding frame 208 is provided with second clearance holes for the pressing cylinders 9 to pass through.

[0026] Specifically, the first drive mechanism includes a fourth drive motor, a fourth reciprocating lead screw connected to the output shaft of the fourth drive motor, and a lead screw nut that cooperates with the fourth reciprocating lead screw. The workpiece slide plate 8 is slidably connected to the top of the bed 1 and is threadedly connected to the fourth reciprocating lead screw through the lead screw nut, so as to realize reciprocating sliding along the length direction of the bed 1.

[0027] Specifically, the clamping cylinder is used to clamp the workpiece, and the floating cylinder is used to adjust the floating state of the fixture 3.

[0028] Specifically, the number of the pressing cylinders 9 is set to at least two, and the working ends of the multiple pressing cylinders 9 are connected together by steel plates and used to assist in pressing the steel billet workpiece to be processed placed on the workpiece slide plate 8.

[0029] Specifically, multiple pressing cylinders 9 are arranged along the length direction of the crossbeam body 201.

[0030] Specifically, the laser surface roughness tester is installed at the bottom of the sliding frame 208 and is used to detect whether the processing and grinding accuracy of the steel billet workpiece meets the process requirements.

[0031] Specifically, the sliding frame 208 is designed to achieve misaligned sliding with the first slide plate 209 and the second slide plate 210. When the first slide plate 209 and the second slide plate 210 slide along the crossbeam body 201, the sliding frame 208 does not need to make any positional adjustments. It can drive the milling head 4, the rough grinding head 5, and the laser surface roughness detector fixed at its bottom, which are respectively located on its left and right sides, to slide back and forth along the length of the crossbeam body 201. This design avoids interference with the displacement movement of the first slide plate 209 and the second slide plate 210, while effectively reducing the length of the crossbeam body 201, enhancing the compactness and stability of the structure, and further improving the machining performance and reliability of the machine tool.

[0032] Specifically, the sliding frame 208 includes a frame body 2081, a square slider 2084, and a T-shaped slider 2085. The frame body 2081 is M-shaped. The square slider 2084 is fixedly connected to the top of the inner cavity of the frame body 2081. The bottom of the frame body 2081 is bent inward. The two T-shaped sliders 2085 are respectively fixedly connected to the left and right sides of the bottom bend of the frame body 2081. The top of the crossbeam body 201 is provided with a square groove 2082, and the bottom of the crossbeam body 201 is provided with two T-shaped grooves 2083. After the frame body 2081 is slidably sleeved and connected to the crossbeam body 201, the square slider 2084 is slidably connected to the square groove 2082, and the T-shaped slider 2085 is slidably connected to the T-shaped groove 2083.

[0033] Specifically, the laser surface roughness detector is installed on either side of the bottom bend of the frame body 2081.

[0034] Specifically, the crossbeam assembly 2 further includes a first drive motor 202 and a first reciprocating screw 203. One end of the first reciprocating screw 203 is rotatably connected to the side wall of the square slide groove 2082, and the other end of the first reciprocating screw 203 passes through the side wall of the square slide groove 2082 and is fixedly connected to the power output end of the first drive motor 202. The square slider 2084 is threadedly connected to the first reciprocating screw 203.

[0035] Specifically, the crossbeam assembly 2 further includes a second drive motor 204, a second reciprocating screw 205, a third drive motor 206, and a third reciprocating screw 207. The second reciprocating screw 205 is fixedly connected to the power output end of the second drive motor 204 and installed in a groove on the side of the crossbeam body 201 near the first slide plate 209. The first slide plate 209 is slidably connected to the crossbeam body 201 through a T-shaped slider groove mechanism, and the first slide plate 209 is threadedly connected to the second reciprocating screw 205.

[0036] After the third reciprocating lead screw 207 is fixedly connected to the power output end of the third drive motor 206, it is installed in the slide groove on the side of the crossbeam body 201 near the second slide plate 210. The second slide plate 210 is slidably connected to the crossbeam body 201 through a T-shaped slider slide groove mechanism, and the second slide plate 210 is threadedly connected to the third reciprocating lead screw 207.

[0037] Specifically, the second drive motor 204 drives the second reciprocating screw 205 to rotate, thereby enabling the first slide plate 209 to slide back and forth along the length of the crossbeam body 201, which in turn drives the ultra-precision grinding head 7 mounted on the first slide plate 209 to move, thus realizing the transverse grinding operation of the steel billet workpiece.

[0038] The third drive motor 206 drives the third reciprocating screw 207 to rotate, thereby enabling the second slide plate 210 to slide back and forth along the length of the crossbeam body 201, which in turn drives the coarse grinding head 5 installed on the second slide plate 210 to move, thus realizing the transverse grinding operation of the steel billet workpiece.

[0039] The first drive motor 202 drives the first reciprocating lead screw 203 to rotate, thereby realizing the reciprocating sliding of the frame body 2081 along the length direction of the crossbeam body 201. This drives the milling head 4, the rough grinding head 5 and the laser surface roughness detector installed on the frame body 2081 to move, realizing the transverse grinding and milling operation of the steel billet workpiece. At the same time, the laser surface roughness detector detects the surface accuracy of the ground steel billet workpiece.

[0040] Specifically, after each milling operation on the steel billet, the frame body 2081 will drive the laser surface roughness detector to perform precision testing on the surface of the processed steel billet. When the surface precision of the steel billet meets the process requirements, the next processing step will begin. If the surface precision does not meet the standard, the steel billet will be reprocessed until the processing precision of the process is met before proceeding to the next process, thereby ensuring the surface processing precision of the steel billet.

[0041] Specifically, the crossbeam assembly 2 further includes a first mounting plate 211, a second mounting plate 212, a third mounting plate 213, and a fourth mounting plate 214. The ultra-precision grinding head 7 is slidably connected to the first slide plate 209 via the first mounting plate 211. The coarse grinding head 5 is slidably connected to the second slide plate 210 via the second mounting plate 212. The milling head 4 is slidably connected to either the left or right side of the sliding frame 208 via the third mounting plate 213. The fine grinding head 6 is slidably connected to the other side of the sliding frame 208 via the fourth mounting plate 214.

[0042] Specifically, motors and lead screw mechanisms are respectively provided on the left and right sides of the first sliding plate 209, the second sliding plate 210 and the sliding frame 208, for driving the lifting and lowering movement of the first mounting plate 211, the second mounting plate 212, the third mounting plate 213 and the fourth mounting plate 214.

[0043] The usage process of this utility model is as follows:

[0044] First, the steel billet workpiece to be processed is placed on the clamp 3 of the workpiece slide plate 8. The clamping cylinder is activated to clamp and fix the workpiece. At the same time, multiple pressing cylinders 9 work together to press down and assist in clamping the workpiece through the linkage steel plate. The floating cylinder adjusts the floating state of the clamp 3 according to the processing requirements. Then, the fourth drive motor is started, and the workpiece slide plate 8 is driven to slide along the length of the bed 1 to the processing station through the fourth reciprocating screw.

[0045] Then, the actions of each processing unit are coordinated by the crossbeam assembly 2. The first drive motor 202 drives the sliding frame 208 to move laterally along the crossbeam body 201, which drives the milling head 4 to the processing position. The lifting mechanism of the third mounting plate 213 adjusts the milling depth. The second drive motor 204 and the third drive motor 206 drive the first slide plate 209 and the second slide plate 210 to move laterally, which drives the ultra-fine grinding head 7 and the rough grinding head 5 to be positioned in the processing area. The processing height is adjusted by the lifting mechanism of the corresponding mounting plate.

[0046] Finally, the machining process is carried out according to the process flow of roughing, finishing and ultra-finishing. First, the milling head 4 completes the surface milling, then the rough grinding head 5 performs the primary grinding, the fine grinding head 6 performs the fine grinding, and finally the ultra-finishing grinding head 7 completes the mirror polishing. After each process is completed, the sliding frame 208 immediately drives the laser surface roughness detector to scan and detect the machined surface. If the accuracy does not meet the process requirements, the current processing is automatically repeated until the detection is qualified and then the next process is entered.
