Description

Technical Field

[0001] This utility model belongs to the field of sanding belt frame technology, specifically a sanding belt frame for grinding pipes. Background Technology

[0002] In the pipe manufacturing industry, belt sanding is a key process for achieving fine surface treatment of pipes. As the core component that supports and drives the sanding belt, the belt sander is usually used by workers in conjunction with the sanding belt to sand the pipes.

[0003] The current pipe grinding belt frame usually consists of a triangular mounting frame, three drive rollers fixed in a triangular shape to the mounting frame, and a motor mounted on the mounting frame. The measured sanding belt is then placed over the three drive rollers, and the sanding belt frame can be operated to grind the pipe.

[0004] However, the grinding of pipe fittings is divided into inner wall and outer wall. When grinding the inner wall, another type of sanding belt frame is required. This type of sander consists of only two drive rollers on the same horizontal plane, which requires additional equipment. Existing pipe fitting grinding sanding belt frames are not convenient to change forms to meet different grinding needs. Therefore, a pipe fitting grinding sanding belt frame is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a pipe grinding sander belt frame is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The pipe grinding sander belt frame of this utility model includes a fixed plate; a first transmission roller is rotatably connected to the front of the fixed plate through a rotating shaft, a second transmission roller is installed on the front of the fixed plate, a transmission plate is rotatably connected to the front of the fixed plate through a transmission ring, and a positioning element is provided on the fixed plate, and the positioning element is used to rotate and position the transmission plate.

[0007] The fixed plate is provided with a positioning mechanism, which includes an extension groove on one side of the transmission plate. An extension block is slidably connected in the extension groove. One end of the extension block extends out of the extension groove. A third transmission roller is rotatably connected to one side of the extension block via a rotating shaft. A first threaded hole is provided on one side of the transmission plate. A first bolt is threaded into the first threaded hole. One end of the first bolt extends out of the first threaded hole and is inserted into a first positioning hole on one side of the extension block. By setting up the positioning mechanism, it is easy to cooperate with the fixed plate to change the shape of the sanding belt frame, thereby adapting it to different usage environments and needs.

[0008] Preferably, the inner wall of the extension groove is provided with a sliding groove, and a slider is slidably connected in the sliding groove. One end of the slider extends out of the sliding groove and is fixedly connected to the extension block. A fixing block is fixedly connected to the inner wall of the sliding groove. The extension block is moved and positioned by the arrangement of the sliding groove, the slider and the fixing block.

[0009] Preferably, a first auxiliary block is fixedly connected to one end of the first bolt, and a first auxiliary ring is fixedly connected to one side of the first auxiliary block near the first bolt. The first auxiliary block and the first auxiliary ring can be used to shield and protect the position of the first bolt, reducing the wear debris from entering the first threaded hole through the intermittent contact between the first bolt and the transmission plate, thus affecting the rotation of the first bolt.

[0010] Preferably, the positioning element includes a second threaded hole on one side of the fixed plate, a second bolt is threaded into the second threaded hole, and one end of the second bolt is inserted into a second positioning hole on one side of the transmission plate. The positioning element is formed by the arrangement and cooperation of the second bolt, the second threaded hole and the second positioning hole.

[0011] Preferably, a second auxiliary block is fixedly connected to one end of the second bolt, and a second auxiliary ring is fixedly connected to one side of the second auxiliary block near the second bolt. The setting of the second auxiliary block and the second auxiliary ring can facilitate the shielding and protection of the position of the second bolt, reduce the wear-generated debris from entering the second threaded hole through the intermittent contact between the second bolt and the fixing plate, and thus affect the rotation of the second bolt.

[0012] Preferably, a handle is fixedly connected to the top of the fixed plate, and the outer wall of the handle is provided with anti-slip texture. The handle makes it easy to hold the sander belt frame for sanding operations when needed.

[0013] Preferably, the outer wall of the first auxiliary ring is provided with anti-slip texture, and the outer wall of the second auxiliary ring is provided with anti-slip texture. The anti-slip texture on the outer wall of the first auxiliary ring increases the friction and prevents slippage when the first auxiliary ring is manually turned. The anti-slip texture on the outer wall of the second auxiliary ring increases the friction and prevents slippage when the second auxiliary ring is manually turned.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a sanding belt holder for pipe grinding. Through the setting of a positioning mechanism, it can be easily matched with a fixing plate to change the shape of the sanding belt holder, thus adapting it to different usage environments and needs. Rotating the first auxiliary ring drives the first bolt to rotate, and rotating the second auxiliary ring drives the second bolt to rotate, moving one end of the second bolt located in the second positioning hole out. Rotating the transmission plate pushes the portion of the extension block located outside back into the extension groove. The first bolt and the second bolt can be reversed sequentially, so that one end of the first thread is inserted into the first positioning hole to move and position the extension block, while one end of the second bolt is inserted into the second positioning hole to limit the rotation of the transmission plate. This allows the sanding belt holder to be converted from a first usage state to a second usage state to adapt to different usage needs. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-4 This utility model provides a pipe sanding belt frame, including a rectangular fixing plate 1, with a handle 14 fixedly connected to the top of the fixing plate 1. The outer wall of the handle 14 is provided with anti-slip texture. The sanding belt frame can be moved to perform sanding operations on pipes by holding the handle 14.

[0026] A cylindrical first transmission roller 2 is rotatably connected to the front of the fixed plate 1 via a rotating shaft. The first transmission roller 2 is composed of two transmission blocks and a transmission column located between the two transmission blocks.

[0027] A cylindrical second transmission roller 3 is mounted on the front side of the fixed plate 1. The second transmission roller 3 has the same structure as the first transmission roller 2.

[0028] The difference is that the second transmission roller 3 is fixedly connected to the output end of the motor that is fixedly installed on the side of the fixed plate 1 away from the first transmission roller 2. The output end of the motor passes through the fixed plate 1 and is rotatably connected to the second transmission roller 3. This motor is a technology known to those skilled in the art, and will not be described in detail or shown in the figure.

[0029] A rectangular transmission plate 4 is rotatably connected to the front of the fixed plate 1 via a circular transmission ring. The transmission plate 4 is located on the side of the fixed plate 1 near the first transmission roller 2.

[0030] The fixed plate 1 is provided with a positioning component, which is used to rotate and position the transmission plate 4. The positioning component includes a second threaded hole 10 opened on one side of the fixed plate 1, and a second bolt 11 is threadedly connected to the second threaded hole 10. One end of the second bolt 11 is inserted into the second positioning hole 12 opened on one side of the transmission plate 4.

[0031] The second bolt 11, the second threaded hole 10, and the second positioning hole 12 are used to form a positioning component for rotating and positioning the transmission plate 4 after the angle is changed.

[0032] A second auxiliary block 13 is fixedly connected to one end of the second bolt 11. A second auxiliary ring is fixedly connected to one side of the second auxiliary block 13 near the second bolt 11. A first fitting groove adapted to the second auxiliary ring is opened on the side of the fixing plate 1 away from the first transmission roller 2. The outer wall of the second auxiliary ring is provided with anti-slip texture to improve friction and prevent slippage when manually moving the second auxiliary ring.

[0033] By setting the second auxiliary block 13 and the second auxiliary ring, in conjunction with the first fitting groove, the position of the second bolt 11 can be easily shielded and protected, reducing the wear-generated debris from entering the second threaded hole 10 through the intermittent contact between the second bolt 11 and the fixing plate 1, thus affecting the rotation of the second bolt 11.

[0034] A positioning mechanism 5 is provided on the fixed plate 1. The positioning mechanism 5 includes a rectangular extension groove 51 opened on one side of the transmission plate 4. A rectangular extension block 52 is slidably connected in the extension groove 51. One end of the extension block 52 extends out of the extension groove 51. A third transmission roller 53 is rotatably connected to one side of the extension block 52 through a rotating shaft.

[0035] A rectangular slide groove 6 is provided on the inner side wall of the extension groove 51. A rectangular slider 7 is slidably connected in the slide groove 6. One end of the slider 7 extends out of the slide groove 6 and is fixedly connected to the extension block 52. A fixing block 8 is fixedly connected to the inner side of the slide groove 6.

[0036] The extension block 52 is guided to move by the slide groove 6 and the slider 7, and the movement of the slider 7 and the extension block 52 is limited by the fixing block 8.

[0037] The third drive roller 53 is not in the extension groove 51. The third drive roller 53 has the same structure as the first drive roller 2. The position of the third drive roller 53 can be adjusted by the transmission plate 4 that can be rotated by the extension block 52 and the extension groove 51, thereby changing the usage state of this sanding belt frame.

[0038] A first threaded hole 56 is provided on one side of the transmission plate 4. A first bolt 54 is threadedly connected to the first threaded hole 56. One end of the first bolt 54 extends out of the first threaded hole 56 and is inserted into the first positioning hole 55 provided on one side of the extension block 52. The first bolt 54, the first positioning hole 55 and the first threaded hole 56 work together to facilitate the movement and positioning of the adjusted extension block 52.

[0039] One end of the first bolt 54 is fixedly connected to the first auxiliary block 9. The first auxiliary block 9 is fixedly connected to the first auxiliary ring on one side near the first bolt 54. A second fitting groove adapted to the first auxiliary ring is opened on one side of the transmission plate 4. The outer wall of the first auxiliary ring is provided with anti-slip texture to improve friction and prevent slippage when manually moving the first auxiliary ring.

[0040] By setting the first auxiliary block 9 and the first auxiliary ring, in conjunction with the second fitting groove, the position of the first bolt 54 can be easily shielded and protected, reducing the wear-generated debris from entering the first threaded hole 56 through the intermittent contact between the first bolt 54 and the transmission plate 4, thus affecting the rotation of the first bolt 54.

[0041] The positioning mechanism 5 allows for easy coordination with the fixing plate 1, enabling the sanding belt frame to change its shape and thus adapt to different usage environments and needs.

[0042] Based on the above structure, this utility model includes the following implementation process;

[0043] This sander belt holder has two usage methods. The first method is:

[0044] When the transmission plate 4 is not rotating, that is, the positions of the first transmission roller 2, the second transmission roller 3 and the third transmission roller 53 are triangular to each other, the sanding belt can be put around the outside of the first transmission roller 2, the second transmission roller 3 and the third transmission roller 53.

[0045] The second way to use it is:

[0046] That is, rotating the first auxiliary ring drives the first bolt 54 to rotate, moving one end of the first bolt 54 out of the first positioning hole 55, thereby releasing the rotation limit on the transmission plate 4;

[0047] Then, rotating the second auxiliary ring causes the second bolt 11 to rotate, moving one end of the second bolt 11 out of the second positioning hole 12, thus releasing the movement and positioning of the extension block 52. The transmission plate 4 can then be rotated from an inclined state to a state parallel to the fixed plate 1. At this time, the third transmission roller 53 should be on the same horizontal plane as the first transmission roller 2 and the second transmission roller 3.

[0048] At the same time, the part of the extension block 52 that is located outside is pushed back into the extension groove 51, so that the part of the extension block 52 that is located outside is halved, so as to avoid the need to equip the adjusted sanding belt frame with a new length of sanding belt, thus reducing unnecessary costs.

[0049] Then the first bolt 54 and the second bolt 11 can be reversed in sequence, so that one end of the first thread is inserted into the first positioning hole 55 to move and position the extension block 52, while one end of the second bolt 11 is inserted into the second positioning hole 12 to limit the rotation of the transmission plate 4.

[0050] The sander belt holder can be switched from the first usage state to the second usage state. The second usage state can be used to grind the inner wall of the pipe. However, it should be noted that the prerequisite for using the second method is that the inner diameter of the pipe should be twice as large as the overall width of the sander belt holder in the second usage state, so as to facilitate the movement of the sander belt holder.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
