Description

Technical Field

[0001] This utility model belongs to the field of belt machine tool technology, specifically a belt machine tool that is easy to grind. Background Technology

[0002] A belt-driven grinding machine is a machine tool that uses a grinding belt to grind and polish the surface of a workpiece. Its working principle is mainly based on the high-speed movement of the grinding belt contacting the workpiece surface to perform grinding. However, the grinding belt needs to be in frequent contact with the workpiece, resulting in severe wear. Since the grinding belt is driven by friction, it must be tensioned on two pulleys, making it inconvenient to disassemble and replace severely worn grinding belts. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a belt-type grinding machine tool that is easy to use. It solves the problem that the grinding belt on the existing belt-type grinding machine tool needs to be in frequent contact with the workpiece, resulting in severe wear. Since the grinding belt is driven by friction, it must be tensioned on two pulleys, which makes it inconvenient to disassemble the grinding belt and difficult to replace the severely worn grinding belt.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a belt milling machine tool that is easy to grind, comprising a housing, a motor fixedly connected inside the housing, a first pulley fixedly connected to the output end of the motor, a fixed rod fixedly connected inside the housing, a lead screw rotatably connected inside the housing via a bearing, a movable plate provided inside the housing, and fixed blocks fixedly connected to both sides of the movable plate, one of the fixed blocks being threadedly connected to the lead screw, and the other fixed block being slidably connected to the fixed rod;

[0005] The movable plate has an inclined groove, and a cylinder is slidably connected inside the inclined groove. A square block is fixedly connected to the top of the cylinder, and a circular plate is fixedly connected to the bottom of the cylinder. A second pulley is rotatably connected to the top of the square block. A sliding groove is provided on the box body, and the square block is slidably connected inside the sliding groove. A frosted belt is fitted on the first pulley and the second pulley.

[0006] As a further embodiment of this utility model: four self-locking casters are fixedly connected to the bottom of the box, and the four self-locking casters are located at the four corners of the bottom of the box.

[0007] As a further embodiment of this utility model: a knob is fixedly connected to one end of the lead screw, and the knob has several grooves.

[0008] As a further embodiment of this utility model: both the first pulley and the second pulley are located at the top of the housing, and the motor is located on one side of the moving plate.

[0009] As a further embodiment of this utility model: the circular plate is located at the bottom of the movable plate, and the square block is located at the top of the movable plate.

[0010] As a further embodiment of this utility model: the first pulley is located on one side of the second pulley, and the two fixed blocks are symmetrically arranged about the middle of the moving plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This easy-to-use belt milling machine, by setting up a first pulley, a second pulley, a sliding groove, a square block, a lead screw, a cylinder, and an inclined groove, allows for disassembly of the grinding belt. When the grinding belt needs to be disassembled, rotating the knob drives the lead screw to rotate. Since one of the fixed blocks is threaded onto the lead screw, its rotation causes the fixed block to move. The fixed block then moves a moving plate. As the moving plate moves, the inclined groove guides the cylinder. Furthermore, because the square block is limited by the sliding groove, it can only move laterally. Under the guiding action of the inclined groove and the limiting action of the sliding groove, the square block and the second pulley move to the left, thereby... By bringing the second pulley closer to the first pulley, the abrasive belt can be loosened and removed. When installing the abrasive belt, first place the belt on the first and second pulleys. Then, rotate the knob in the opposite direction to reverse the screw. Similar to removing the belt, the reverse screw will move the second pulley away from the first pulley, thus tensioning the belt and completing the installation. This machine tool achieves the tensioning and loosening of the abrasive belt by changing the distance between the first and second pulleys, making it easy to install and remove the belt and convenient to replace severely worn belts.

[0013] 2. This easy-to-use belt polishing machine tool, through the configuration of a motor, a first pulley, a housing, and self-locking casters, allows the grinding belt to operate when the belt is taut. The motor drives the first pulley to rotate, thus enabling the belt to move. The workpiece to be polished is brought close to the abrasive surface of the belt, and the relative motion between the belt and the workpiece polishes it. When the machine tool needs to be moved, the housing is pushed, causing the self-locking casters to roll on the ground, thus moving the machine tool. Once the machine tool is moved to the designated location, the self-locking casters are locked to secure it. The machine tool's operation, facilitated by the motor driving the belt, allows for easy polishing of workpieces. Furthermore, the self-locking casters reduce friction between the housing and the ground, facilitating movement. Locking the casters after movement enhances the machine tool's stability.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a belt milling machine tool that is easy to grind, including a housing 1, a motor 7 fixedly connected inside the housing 1, a first pulley 3 fixedly connected to the output end of the motor 7, and a fixed rod 9 fixedly connected inside the housing 1. Because of the fixed rod 9, when the moving plate 10 moves, the fixed block 14 will slide on the fixed rod 9. The fixed rod 9 plays a role in limiting and guiding the fixed block 14 and the moving plate 10, improving the stability and accuracy of the movement of the moving plate 10. Moreover, the fixed rod 9 can also prevent the moving plate 10 from rotating with the lead screw 8, so that the moving plate 10 can move normally when the lead screw 8 rotates. The lead screw 8 is rotatably connected inside the housing 1 through a bearing. A knob 15 is fixedly connected to one end of the lead screw 8. The knob 15 has several grooves. Because the knob 15 has several grooves, it can increase friction, making it convenient for personnel to rotate the knob 15 and improving the ease of operation.

[0021] The housing 1 has a movable plate 10 inside, and fixed blocks 14 are fixedly connected to both sides of the movable plate 10. One of the fixed blocks 14 is threaded to the lead screw 8, and the other fixed block 14 is slidably connected to the fixed rod 9. The movable plate 10 has a slanted groove 16. The first pulley 3 is located on one side of the second pulley 4. The two fixed blocks 14 are symmetrically arranged about the middle of the movable plate 10.

[0022] A cylinder 12 is slidably connected inside the inclined groove 16. A square block 11 is fixedly connected to the top of the cylinder 12. The square design of the square block 11, together with the limiting effect of the sliding groove 6, prevents the square block 11 from rotating, thus ensuring the stability of the overall structure. A circular plate 13 is fixedly connected to the bottom of the cylinder 12. The circular plate 13 is located at the bottom of the moving plate 10, and the square block 11 is located at the top of the moving plate 10. A second pulley 4 is rotatably connected to the top of the square block 11. A sliding groove 6 is provided on the housing 1. Because of the sliding groove 6, the sliding groove 6 can limit and guide the square block 11, so that the square block 11 and the second pulley 4 can only move laterally, improving the stability and accuracy of the movement of the second pulley 4.

[0023] The square block 11 is slidably connected inside the slide groove 6. The first pulley 3 and the second pulley 4 are fitted with a frosted belt 5. Because of the frosted belt 5, the first pulley 3 is rotated by starting the motor 7 to make the frosted belt 5 work, which facilitates the polishing of the items. Four self-locking universal wheels 2 are fixedly connected to the bottom of the box body 1. The four self-locking universal wheels 2 are located at the four corners of the bottom of the box body 1. The first pulley 3 and the second pulley 4 are both located at the top of the box body 1. The motor 7 is located on one side of the moving plate 10.

[0024] The working principle of this utility model is as follows:

[0025] When the abrasive belt 5 needs to be disassembled, turning the knob 15 causes the lead screw 8 to rotate. Since one of the fixing blocks 14 is threadedly connected to the lead screw 8, when the lead screw 8 rotates, the fixing block 14 will move. The fixing block 14 drives the moving plate 10 to move. As the moving plate 10 moves, the inclined groove 16 provides a guide for the cylinder 12. And because the square block 11 is limited by the sliding groove 6, the square block 11 can only move laterally. Under the guiding action of the inclined groove 16 and the limiting action of the sliding groove 6, This causes the square block 11 and the second pulley 4 to move to the left, thereby bringing the second pulley 4 closer to the first pulley 3 and loosening the frosted belt 5. The frosted belt 5 can then be disassembled. When it is necessary to install the frosted belt 5, first put the frosted belt 5 on the first pulley 3 and the second pulley 4. At this time, turn the knob 15 in the opposite direction to drive the screw 8 to reverse. The same principle applies when disassembling the frosted belt 5. The reverse rotation of the screw 8 will cause the second pulley 4 to move away from the first pulley 3, thereby tightening the frosted belt 5 and completing the installation of the frosted belt 5.

[0026] When the abrasive belt 5 is in a taut state, the start motor 7 drives the first pulley 3 to rotate, thereby making the abrasive belt 5 operate. The object to be polished is brought close to the abrasive surface of the abrasive belt 5, and the object is polished by the relative movement between the belt and the object. When the machine tool needs to be moved, the housing 1 is pushed to make the self-locking universal wheel 2 roll on the ground, thereby moving the machine tool. When the machine tool is moved to the designated position, the self-locking universal wheel 2 is locked to fix the machine tool.
