Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a grinding belt installation mechanism. Background Art

[0002] Castings are metal objects obtained through various casting methods. Specifically, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction, or other casting methods. After cooling, it undergoes subsequent processing such as polishing to create an object with a defined shape, size, and properties. Castings are a key component of the heavy equipment manufacturing industry. The upstream raw materials of the casting industry chain are primarily pig iron and scrap steel, and their applications are diverse, including but not limited to machine tools, automobiles, instrumentation, shipbuilding, and aerospace. The development of these sectors places extremely high demands on castings and the technical requirements are therefore considered a vital component of advanced manufacturing.

[0003] After the casting is produced, it needs to be processed to form the final product. The processing includes cutting, grinding, shot blasting, etc. In the manufacturing of castings, defects such as sand holes, burrs, and pouring risers may appear. In order to remove these defects or improve the quality and aesthetics of the casting, the casting needs to be polished. Polishing is generally carried out by driving the grinding belt to rotate through the drive structure, and the casting is polished by contacting the grinding belt. The rotation of the grinding belt requires the grinding belt to be straight to ensure the connection and transmission performance of the drive structure and the grinding position. However, if the distance between the structure for installing the grinding belt at the grinding position and the drive structure is fixed, it will be inconvenient to install the grinding belt (because the distance for installing the grinding belt (the distance between the grinding position and the drive structure) generally needs to be less than the distance when the grinding belt is straightened for transmission, otherwise it will not be installed or will be difficult to install). Therefore, it is necessary to adjust the distance between the grinding structure and the drive structure at the grinding position to facilitate the installation of the grinding belt, and after installation, the grinding belt can be straightened for transmission grinding.

In actual use and application, the actual direction shall prevail.

[0026] Example 1

[0027] This embodiment provides a grinding belt installation mechanism, and its specific structure is as follows: Figure 1 and 2As shown, it includes a mounting seat 1, a grinding frame 2, a main drive structure 3, a slave drive structure 4, a grinding structure 5 and a connecting structure 6. The grinding frame 2 is arranged above the mounting seat 1 and extends forward. The main drive structure 3 and the slave drive structure 4 are both located in the grinding frame 2.

A motor 8 is provided in the mounting seat 1. The output shaft 9 of the motor 8 passes upward through the mounting seat 1, the grinding frame 2 and the main drive structure 3 for transmission connection.

[0028] When a grinding belt installation mechanism of this embodiment is used, the grinding structure 5 is moved backward by moving the connecting structure 6 backward, and the grinding belt 7 is sleeved on the main drive structure 3, the slave drive structure 4, and the grinding structure 5. The main drive structure 3 is driven to rotate by the motor 8, which drives the grinding belt 7 to rotate. The casting is placed on the grinding belt 7 at the position of the grinding structure 5 for grinding. The grinding belt 7 is easy and quick to install.

[0041] The rest is the same as Example 2.

[0042] After the grinding belt 7 in this embodiment is sleeved on the driving wheel 31, the driven wheel 42 and the grinding cylinder 54, the motor 1 drives the grinding belt 7 to rotate indirectly to grind the casting. The detachable setting of the connecting plate 52 and the connecting block 51 facilitates the repair and replacement of the grinding structure 5.

[0044] The connection structure 6 of this embodiment includes a connection frame 61, such as Figure 4-6 As shown, a sliding block 62 is provided in the connecting frame 61, and the sliding block 62 is connected to the rear end of the connecting block 51. Two sliding long grooves 63 are symmetrically provided on both sides of the connecting frame 61, and two limit blocks 64 are provided on both sides of the sliding block 62 corresponding to the two sliding long grooves 63. The two limit blocks 64 are provided outside the connecting frame 61 and are connected to the sliding block 62 through two connecting rods 65 respectively; each sliding long groove 63 is provided with two vertical grooves 66, and each vertical groove 66 corresponds to an L-shaped limit plug-in 67, and the limit plug-in 67 includes an inserting portion 671 and a limit portion 672.

[0045] Preferably, the vertical slots 66 are arranged in such a manner that when the sliding block 62 is placed between two vertical slots 66 on the same side, the grinding belt 7 is stretched and driven to connect the grinding structure 5 , the main drive structure 3 and the slave drive structure 4 .

[0046] The rest is the same as Example 4.

[0047] When using this embodiment, when the grinding belt 7 needs to be installed, the limiting plug-in 67 is removed, and the grinding structure 5 is pushed backward, driving the sliding block 62 to compress the spring 68 backward in the connecting frame 61 and move. After the grinding belt 7 is put on, the grinding structure 5 is moved forward until the grinding belt 7 is stretched and in a state ready for transmission and grinding. At this time, the sliding block 62 is located between the two vertical grooves 66 on the same side. The limiting plug-in 67 is inserted into the vertical grooves 66 from both sides of the sliding block 62 so that the sliding block 62 is located between the two limiting plug-in 67 on the same side. The sliding block 62 is fixed in position to ensure that the grinding belt 7 is stretched and in a state ready for transmission and grinding. When the grinding belt 7 needs to be removed, the limiting plug-in 67 is removed and the grinding structure 5 is moved to remove and replace it.

[0048] Example 6

[0049] In this embodiment, threaded holes 69 are provided on both sides of the sliding block 62 at positions corresponding to the sliding long grooves 63.

[0050] The rest is the same as Example 5.

[0051] This embodiment is based on the embodiment 5. After the grinding belt 7 is installed and the limiting plug-in 67 is inserted for limiting, the bolt is screwed into the sliding block 62 so that the nut squeezes the connecting frame 61 to further fix the sliding block 62, that is, the grinding structure 5 is fixed, to avoid the unstable fixation of the grinding structure 5 affecting the transmission rotation of the grinding belt 7 and affecting the use of the equipment.
