Description

Technical Field

[0001] This utility model relates to the field of machine tool processing, and in particular to a low-guide machine tool door. Background Technology

[0002] Machine tool doors are usually movable. A cover is installed on the worktable, which also covers the machine tool. The upper part of the machine tool door is slidably mounted on the cover, and the bottom is equipped with a slide rail. The bottom of the machine tool door is mounted on the slide rail. However, during the mechanical processing, waste chips and dust are generated. These waste chips and dust will accumulate on the sliding path at the bottom of the machine tool door, causing the machine tool door to be pushed up or stuck during the movement, making it difficult to close the machine tool door. Utility Model Content

[0003] The purpose of this invention is to provide a low-profile machine tool door that solves the problem of blocked movement path of the machine tool door.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a low-guide machine tool door for mounting on a machine tool's worktable, comprising a drive assembly, a guide assembly, and a door body. The drive assembly includes a motor, a sling, a drive wheel, and a driven wheel. The drive wheel is connected to the drive end of the motor, and the two ends of the sling are respectively sleeved on the drive wheel and the driven wheel. The guiding assembly includes a guide plate, a slide plate, a first guide wheel, and a second guide wheel. The first guide wheel and the second guide wheel are rotatably mounted on the slide plate, and the first guide wheel and the second guide wheel rotatably abut against both ends of the guide plate in the length direction. The door body is connected to the sling and the slide at both ends, and the height of the guide plate is lower than the workbench surface.

[0005] Optionally, the drive assembly further includes a positioning plate, which comprises an upper plate, a lower plate, and a middle plate. The two ends of the middle plate are respectively connected to the upper plate and the lower plate. The drive wheel and the driven wheel are rotatably mounted on the middle plate, and the sling is located between the upper plate and the lower plate. Optionally, it also includes a sliding mechanism, which includes a hanging block, a hanging seat, a first pulley and a second pulley. The hanging block is disposed on the hanging belt, and the two ends of the hanging seat are respectively connected to the hanging block and the door body. The first pulley and the second pulley are rotatably disposed on the hanging seat.

[0006] Furthermore, the lower plate has a slide rail located below the sling, and the first pulley and the second pulley are slidably disposed on the slide rail.

[0007] Furthermore, the bottom of the lifting block has a first lifting lug and a second lifting lug, which are connected to the lifting base.

[0008] Furthermore, the lifting block includes an upper lifting plate and a lower lifting plate. The upper lifting plate is located above the lower lifting plate, and an interlocking space is formed between the upper lifting plate and the lower lifting plate. The lifting strap is located within the interlocking space. The bottom surface of the upper lifting plate has upper teeth, and the top surface of the lower lifting plate has lower teeth. The upper teeth and the lower teeth interlock with the lifting strap.

[0009] Furthermore, the first guide wheel has a first annular groove on its outer periphery, and the second guide wheel has a second annular groove on its outer periphery, with the first annular groove and the second annular groove overlapping on the slide rail.

[0018] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] like Figure 1 and Figure 2 and Figure 3 As shown, a low-guide machine tool door is used to be installed on the worktable of a machine tool. It includes a drive assembly 1, a guide assembly 2 and a door body 3. The drive assembly 1 drives the door body 3 to move, and the guide assembly 2 guides the door body 3. The drive assembly 1 is installed on the cover 6 and the guide assembly 2 is installed on the worktable 5.

[0020] The drive assembly 1 includes a motor 11, a sling 12, a drive wheel 13, and a driven wheel 14. The drive wheel 13 and the driven wheel 14 are rotatably mounted on the housing 6. The drive wheel 13 is connected to the drive end of the motor 11. In this example, the drive wheel 13 is connected to the drive end of the motor 11 via a belt (not shown in the figure). The two ends of the sling 12 are respectively sleeved on the drive wheel 13 and the driven wheel 14. When the motor 11 drives the drive wheel 13 to rotate via the belt, the drive wheel 13 drives the driven wheel 14 to rotate via the sling 12.

[0021] The guide assembly 2 includes a guide plate 21, a slide plate 22, a first guide wheel 23, and a second guide wheel 24. The first guide wheel 23 and the second guide wheel 24 are rotatably mounted on the slide plate 22. The first guide wheel 23 and the second guide wheel 24 rotatably abut against both ends of the guide plate 21 in the length direction. The two ends of the door body 3 are respectively connected to the lower layer of the sling 12 and the slide plate 22. The guide plate 21 is mounted on the workbench 5, and the first guide wheel 23 and the second guide wheel 24 are located above the workbench 5.

[0022] The fixing rod 8 passes upward through the folding plate 31, and the folding plate 31 and the sliding plate 22 are fixed together by the fixing rod 8, which extends into the clearance cavity 32.

[0023] like Figure 4 As shown, a fixed rod 8 is provided on the slide plate 22. The first guide wheel 23 and the second guide wheel 24 are rotatably mounted on the fixed rod 8. When the sling 12 rotates, the door 3 will move together with the lower layer of the sling 12. The slide plate 22 moves together with the door 3. The first guide wheel 23 and the second guide wheel 24 roll and rub against the two sides of the guide plate 21 respectively. In this way, the movement of the bottom of the door 3 is restricted, and the bottom position of the door 3 will not shift. That is, the door 3 will not shake during movement.

[0024] The height of the guide plate 21 should be lower than the table surface 7 of the worktable 5. The workpiece to be processed should be placed on the table surface 7, and the height of the guide plate 21 should be lower than the table surface 7. This makes it easier for the workpiece to cross the guide plate 21 and facilitates the handling of the workpiece.

[0025] The drive assembly 1 also includes a fixing plate 15. The positioning plate 15 includes an upper plate 151, a lower plate 152 and an intermediate plate 153. The two ends of the intermediate plate 153 are respectively connected to the upper plate 151 and the lower plate 152. The fixing plate 15 is set on the cover 6 and is fixed to the cover 6 by bolts. The drive wheel 13 and the driven wheel 14 are rotatably set on the intermediate plate 153. The sling 12 is located between the upper plate 151 and the lower plate 152. The upper plate 151 and the lower plate 152 have a protective function for the sling 12 to prevent the sling 12 from being touched.

[0026] like Figure 5 As shown, the guide plate 21 includes a vertical plate 211 and a horizontal plate 212 formed by bending. The first guide wheel 23 and the second guide wheel 24 rotate and abut against both ends of the vertical plate 211 in the length direction. The horizontal plate 212 extends towards the outer end of the worktable 5 and is fixed to the worktable 5 by bolts. The horizontal plate 212 supports the vertical plate 211. The top of the vertical plate 211 is lower than the table surface 7.

[0027] The skateboard 22 includes a first side plate 221, a second side plate 222, and a top plate 223. The first side plate 221 and the second side plate 222 are respectively connected to the two ends of the top plate 223. The top plate 223 is located above the guide plate 21 and above the vertical plate 211. The first guide wheel 23 and the second guide wheel 24 are rotatably mounted on the top plate 223. The vertical plate 211 is located between the first side plate 221 and the second side plate 222.

[0028] like Figure 6 As shown, it also includes a sliding mechanism 4, which includes a hanging block 41, a hanging seat 42, a first pulley 43, and a second pulley 44. The hanging block 41 is mounted on the sling 12. The two ends of the hanging seat 42 are connected to the hanging block 41 and the door body 3, respectively. The sling 12 drives the hanging block 41 to move, and the hanging block 41 drives the hanging seat 42 and the door body 3 to move. The first pulley 43 and the second pulley 44 are rotatably mounted on the hanging seat 42. The first pulley 43 and the second pulley 44 move on the cover 6, so that the first pulley 43 and the second pulley 44 keep moving horizontally. The cover 6 provides support for the first pulley 43 and the second pulley 44, which can prevent the sliding mechanism 4 from falling up and down on the sling 12, that is, to keep the lower layer of the sling 12 always horizontal.

[0029] The lower plate 152 has a slide rail 45, which is located below the sling 12. The first pulley 43 and the second pulley 44 are slidably mounted on the slide rail 45 so that the sliding trajectory of the first pulley 43 and the second pulley 44 will not deviate.

[0030] The first pulley 43 has a first annular groove 430 on its outer periphery, and the second pulley 44 has a second annular groove 440 on its outer periphery. The first annular groove 430 and the second annular groove 440 overlap on the slide rail 45, so that the first pulley 43 and the second pulley 44 are not easy to fall off the slide rail 45 during movement.

[0031] The bottom of the lifting block 41 has a first lifting lug 411 and a second lifting lug 412. The first lifting lug 411 and the second lifting lug 412 are connected to the lifting base 42. The first lifting lug 411 and the second lifting lug 412 are connected to the lifting base 42 by bolts.

[0032] The bottom of the lifting block 41 also has a reverse folding plate 46, which is located between the first lifting lug 411 and the second lifting lug 412. The reverse folding plate 46 extends horizontally, while the first lifting lug 411 and the second lifting lug 412 extend vertically. The reverse folding plate 46 extends into the lifting base 42 and can move up and down on the lifting base 42. The positions of the first lifting lug 411 and the second lifting lug 412 on the lifting base 42 can be adjusted, and the reverse folding plate 46 can make the lifting block 41 more stable.

[0033] The lifting block 41 includes an upper lifting plate 413 and a lower lifting plate 414. The upper lifting plate 413 is located above the lower lifting plate 414, and an interlocking space 400 is formed between the upper lifting plate 413 and the lower lifting plate 414. The lifting strap 12 is located in the interlocking space 400. The bottom surface of the upper lifting plate 413 has upper teeth 415, and the top surface of the lower lifting plate 414 has lower teeth 416. The upper teeth 415 and the lower teeth 416 interlock together with the lifting strap 12, so that the strap 12 is not easy to fall off from the interlocking space 400.

[0034] A folding plate 31 is provided at the bottom of the door body 3. The folding plate 31 is connected to the sliding plate 22. The folding plate 31 has a clearance cavity 32. The clearance cavity 32 is arranged opposite to the sliding plate 22. The clearance cavity 32 is located on the upper part of the folding plate 31, and the sliding plate 22 is located under the folding plate 31.
