Description

Technical Field

[0001] This utility model relates to the field of industrial production, and in particular to a variable multi-purpose belt polisher. Background Technology

[0002] In modern industrial production, belt sanders, as a highly efficient surface finishing device, are widely used in various fields such as machinery manufacturing, automotive parts processing, and furniture manufacturing. The sanding fixture, as a key component of the belt sander, directly affects the quality and efficiency of the sanding operation. In actual production, the sanding fixture often needs to be changed to meet diverse sanding tasks according to different processing requirements.

[0003] Currently, existing belt sanders generally employ a structural design that secures the mounting parts in at least two directions when fixing the grinding fixture. While this multi-directional fixing method ensures the stability of the grinding fixture during operation, it requires operators to disassemble the fixing parts in both directions separately when changing the grinding fixture. This not only involves cumbersome procedures and consumes a lot of time and energy, but also increases labor intensity and reduces production efficiency.

[0004] Therefore, it is necessary to provide a variable multi-purpose belt polisher to solve the above-mentioned technical problems. Utility Model Content

A front side plate is fixed to the side of the base near the front, and the telescopic sleeve is fixedly connected to the front side plate. The mounting chamber is disposed above the base to fix the grinding mechanism, which is located in front of the front side plate. The feature is that a horizontal fixing column and a vertical fixing column are disposed inside the mounting chamber, and an inclined plate is disposed above the base. The inclined plate is inclined relative to the base, and a pull plate is fixedly connected to the left side of the inclined plate. The inclined plate can slide horizontally relative to the base, causing the horizontal and vertical fixing columns to slide simultaneously within the mounting chamber, so that they detach from or insert into the mounting chamber.

[0009] Preferably, a telescopic column is sleeved inside the telescopic sleeve, and a lead screw groove is opened at one end of the telescopic column near the telescopic sleeve. A threaded groove is opened on the inner surface of the lead screw groove. A telescopic motor is installed on the inner wall of the telescopic sleeve away from the telescopic column.

The horizontal fixing column is set in the installation hole on the side of the installation chamber away from the telescopic column. The installation chamber is also provided with an installation block. The installation block is connected to the grinding mechanism. The top and side of the installation block are both provided with fixing holes corresponding to the installation holes.

[0011] Preferably, the grinding mechanism includes: a double-wheel support plate, a drive disc, a tension disc, and a sanding belt.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] See Figures 1 to 4 This is the first embodiment of the present invention. A variable multi-purpose belt sander includes: a base 10, a telescopic sleeve 40, a telescopic column 41, a mounting chamber 50, a grinding mechanism 60, and an inclined plate 70. A front side plate 11 is fixedly connected to the side of the base 10 near the front. The telescopic sleeve 40 is disposed on the front side plate 11. The telescopic column 41 is sleeved inside the telescopic sleeve 40. The mounting chamber 50 is disposed at the end of the telescopic column 41 away from the telescopic sleeve 40. The grinding mechanism 60 is disposed on the front side plate 11. The inclined plate 70 is disposed on the mounting chamber 50. When the grinding mechanism 60 is replaced to change the grinding contact surface, the inclined plate 70 on the mounting chamber 50 is moved to disconnect the connection between the mounting chamber 50 and the grinding mechanism 60. The telescopic column 41 can slide inside the telescopic sleeve 40, so that the mounting chamber 50 moves away from or closer to the telescopic sleeve 40, changing the spacing between the internal components of the grinding mechanism 60.

[0023] A grinding motor 20 is installed on the right side of the base 10. The driving end of the grinding motor 20 is connected to the grinding mechanism 60. A cylinder 30 is fixedly connected to the top of the base 10. The cylinder 30 is located on the back of the front side plate 11. A connecting rod 301 is fixedly connected to the telescopic end of the cylinder 30. A tensioning limiting block 32 is fixedly connected to the top of the connecting rod 301. A groove plate 31 is fixedly connected to the top of the front side plate 11. The tensioning limiting block 32 is slidably connected to the groove plate 31. The cylinder 30 drives the connecting rod 301 to move up and down, which can drive the tensioning limiting block 32 to slide on the groove plate 31.

[0024] The telescopic column 41 has a lead screw groove 411 at one end near the telescopic sleeve 40. The inner surface of the lead screw groove 411 has a threaded groove. The telescopic motor 42 is installed on the inner wall of the telescopic sleeve 40 away from the telescopic column 41. The drive end of the telescopic motor 42 is fixedly connected to the telescopic lead screw 421. The outer surface of the telescopic lead screw 421 is threaded to the inner wall of the lead screw groove 411. The outer surface of the telescopic sleeve 40 has a heat dissipation groove 43, which is located outside the telescopic motor 42. Both the telescopic column 41 and the telescopic sleeve 40 are square. The telescopic motor 42 can drive the telescopic lead screw 421 to rotate. Through the threaded connection, the telescopic column 41 moves inside the telescopic sleeve 40, causing the distance between the mounting chamber 50 on the telescopic column 41 and the grinding motor 20 to change.

[0025] Mounting holes 501 are provided on the top of the mounting chamber 50 and on the side away from the telescopic column 41. A vertical fixing column 51 is installed inside the mounting hole 501 on the top of the mounting chamber 50, and a wedge block 511 is fixedly connected to the top of the vertical fixing column 51. The wedge block 511 can slide on the upper surface of the inclined plate 70 when it slides horizontally. A horizontal fixing column 52 is installed inside the mounting hole 501 on the side of the mounting chamber 50 away from the telescopic column 41. A mounting block 53 is also provided inside the mounting chamber 50. The mounting block 53 is connected to the grinding mechanism 60, and its top and side are provided with mounting holes 501. The vertical fixing post 51 can be simultaneously inserted into the mounting hole 501 on the top of the mounting chamber 50 and the corresponding fixing hole 531, and the horizontal fixing post 52 can be simultaneously inserted into the mounting hole 501 on the side of the mounting chamber 50 and the corresponding fixing hole 531, fixing the mounting block 53 inside the mounting chamber 50. A spring-loaded pad is provided between the mounting chamber 50 and the mounting block 53. After the mounting block 53 is fixed, it can be pushed outward. Due to the restriction of the vertical fixing post 51 and the horizontal fixing post 52, the mounting block 53 is tightly fixed inside the mounting chamber 50.

[0026] The grinding mechanism 60 includes a double-wheel support plate 61, a drive disc 62, a tensioning disc 63, and a sanding belt 64. The double-wheel support plate 61 is fixedly connected to the mounting block 53. The drive disc 62 is fixedly connected to the drive end of the grinding motor 20. The tensioning disc 63 is fixedly connected to the tensioning limiting block 32. When the tensioning limiting block 32 moves up and down, it can drive the tensioning disc 63 to move up and down, adjusting the tension of the sanding belt 64. The sanding belt 64 is mounted on the drive disc 62, the tensioning disc 63, and the double-wheel support plate 61 to transmit power. The telescopic column 41 can drive the double wheels. The support plate 61 moves closer to or further away from the drive disc 62 to accommodate sanding belts 64 of different lengths. The two wheels of the dual-wheel support plate 61 form a flat grinding surface, which can provide uniform grinding force when grinding materials with high hardness and that are not easily deformed. It can effectively remove oxide scale, burrs, and weld excess on the metal surface and is suitable for processing regular flat surfaces. The back of the dual-wheel support plate 61 is fixedly connected to the mounting block 53. By pushing the inclined plate 70, the fixed relationship between the mounting chamber 50 and the mounting block 53 can be released, realizing the quick change of the dual-wheel support plate 61.

[0027] The upper surface of the inclined plate 70 is provided with an inclined groove 701, which is adapted to the vertical fixed column 51. The inclined plate 70 is inclined relative to the base 10. A pull plate 71 is fixedly connected to the side of the inclined plate 70 away from the telescopic column 41. A spring 72 is provided between the pull plate 71 and the mounting chamber 50, and the spring 72 is wrapped around the outside of the horizontal fixed column 52. The side of the pull plate 71 near the spring 72 is fixedly connected to the horizontal fixed column 52. Guide rods 73 are fixedly connected to the back of both the pull plate 71 and the inclined plate 70. A guide ring 731 is provided below the inclined plate 70 and is fixedly connected to the mounting chamber 50. The sliding connection is inside the guide ring 731. When the pull plate 71 is pulled manually, the horizontal fixing column 52 is disengaged from the mounting chamber 50, releasing the lateral restriction. At the same time, the inclined plate 70 moves, and the inclined block 511 is located above the inclined groove 701. When the inclined groove 701 moves, the inclined block 511 slides above the inclined groove 701. Due to the inclined setting of the inclined plate 70, the inclined block 511 drives the vertical fixing column 51 to move upward, releasing the vertical restriction. The mounting block 53 can be disengaged from the mounting chamber 50, and the grinding mechanism 60 can be quickly replaced. During installation, the mounting block 53 is fixed by the opposite operation, and the spring 72 retracts to reset the pull plate 71.

[0028] The working principle of the variable multi-purpose belt polisher provided by this utility model is as follows:

[0029] Manually pull the pull plate 71, causing the inclined plate 70 to slide to the right in the horizontal direction (the guide rod 73 slides and guides within the guide ring 731). The horizontal fixing column 52 moves to the right with the pull plate 71, disengaging from the mounting hole 501 on the side of the mounting chamber 50 and the fixing hole 531 of the mounting block 53, thus releasing the horizontal fixation. The inclined groove 701 on the inclined plate 70 moves to the right simultaneously. Because the inclined plate 70 is set at an inclination, the inclined block 511 at the top of the vertical fixing column 51 slides upward along the inclined surface of the inclined groove 701, causing the vertical fixing column 51 to disengage from the mounting hole 501 at the top of the mounting chamber 50 and the fixing hole 531 of the mounting block 53, thus releasing the vertical fixation. At this time, the mounting block 53 and the grinding mechanism 60 are completely disengaged from the mounting chamber 50, and the old tooling can be directly removed.

[0030] Align the mounting block 53 of the new grinding mechanism 60 with the mounting chamber 50, insert it into the fixing hole 531 and align it with the mounting hole 501, release the pull plate 71, the spring 72 returns to its original position and pushes the pull plate 71 to move to the right, the horizontal fixing column 52 is re-inserted into the side of the mounting chamber 50 and the fixing hole 531 of the mounting block 53, the vertical fixing column 51 slides down along the inclined groove 701 due to the rightward movement of the inclined plate 70, and is inserted into the top of the mounting chamber 50 and the fixing hole 531 of the mounting block 53, the mounting block 53 is locked by the horizontal fixing column 52 and the vertical fixing column 51, at the same time the rebound pad pushes the mounting block 53 outward and presses it against the inner wall of the mounting chamber 50 to ensure a firm fixation;

[0031] The grinding motor 20 drives the drive disc 62 to rotate, which in turn drives the tension disc 63 and the double wheel support plate 61 to rotate synchronously through the sanding belt 64, thus realizing the transmission of grinding power. The cylinder 30 drives the connecting rod 301 to move up and down, which drives the tension limiting block 32 and the tension disc 63 to slide along the groove plate 31, thereby adjusting the tension of the sanding belt 64 in real time to prevent slippage or breakage.

[0032] refer to Figure 5 This is the second embodiment of the present invention. Unlike the first embodiment, the grinding mechanism 60 includes a drive disc 62, a tension disc 63, a sanding belt 64, and a large support wheel 65. The sanding belt 64 is mounted on the outside of the drive disc 62, tension disc 63, sanding belt 64, and large support wheel 65 to provide grinding power. The diameter of the large support wheel 65 is larger than that of the drive disc 62, forming a large-arc grinding surface. This provides a larger contact area when grinding thin metal sheets, large-sized stone slabs, and other materials. For example, when grinding thin metal sheets, a flat grinding surface can easily cause excessive pressure at both ends, leading to sheet deformation. The large-arc grinding surface, while approaching a flat surface, retains a slight curvature. During grinding, the curved surface rolls and contacts, resulting in a gentler pressure distribution on the material surface. This is suitable for easily deformable sheet materials. A mounting block 53 is also fixedly connected to the back of the large support wheel 65 and is compatible with the mounting chamber 50, enabling quick replacement of the large support wheel 65 and achieving the purpose of rapid changing of the grinding fixture.

[0033] refer to Figure 6This is the third embodiment of the present invention. Unlike the first embodiment, the grinding mechanism 60 includes a drive disc 62, a tension disc 63, a sanding belt 64, and a small support wheel 66. The sanding belt 64 is mounted on the outside of the drive disc 62, tension disc 63, sanding belt 64, and small support wheel 66 to provide grinding power. The diameter of the small support wheel 66 is smaller than that of the drive disc 62, forming a small-arc grinding surface. When grinding small pipes and small furniture, the small-arc grinding surface can closely adhere to these small objects. For fine grinding of surfaces, such as plastic pipes, large-arc grinding surfaces often cannot fit the pipe surface well. Using small-arc grinding surfaces can better fit the pipe surface. The pipe surface is ground thoroughly to remove dirt or as a pretreatment before applying anti-corrosion coating. It is suitable for various materials that require arc transitions, curved surface polishing, or edge rounding. The small support wheel 66 is also fixedly connected to the back of the mounting block 53, which is compatible with the mounting chamber 50, so as to realize the quick replacement of the small support wheel 66 and achieve the purpose of quick replacement of grinding tooling.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
