DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 3 In the embodiment of the utility model, a rubber part reaming device comprises a workbench 1 and a support frame 2 welded to the top of the workbench 1. A reaming groove 6 is provided in the middle of the top of the workbench 1. A driving assembly for driving the lifting and lowering during reaming is provided on the top of the inner wall of the support frame 2. The driving assembly comprises a motor 31, a bidirectional screw 32, a moving block 33, a lifting rod 34 and a support plate 35. A motor 31 is installed on the top of one side of the support frame 2 by bolts. A bidirectional screw 32 is fixedly installed on the output shaft of the motor 31. One end of the bidirectional screw 32 penetrates the support frame 2 and is rotatably connected to the inner wall of the support frame 2 through a bearing seat. The surface of the bidirectional screw 32 is rotatably connected with two moving blocks 33 by threads. The bottom ends of the two moving blocks 33 are respectively hingedly connected with lifting rods 34. One end of the lifting rod 34 away from the moving block 33 is hingedly connected to the top surface of the support plate 35.

[0021] When in use, the motor 31 is started, and when the output shaft of the motor 31 rotates, the bidirectional screw 32 is driven to rotate synchronously, so that the moving blocks 33 on the surface of which are threadedly connected move away from or towards each other. When the moving blocks 33 move closer to each other, the lifting rod 34 hingedly connected to the bottom end thereof is driven to move synchronously. At the same time, the other end of the lifting rod 34 drives the support plate 35 to move downward. When the moving blocks 33 move away from each other, one end of the lifting rod 34 is driven to move in the same direction. At this time, the other end of the lifting rod 34 drives the support plate 35 to move upward.

[0022] The middle part of the bottom surface of the support plate 35 is movably connected with the expansion column 7 by facilitating the installation of the assembly. The installation assembly includes a sleeve 41, a positioning block 42, a fixing rod 43 and a first spring 44. The middle part of the bottom surface of the support plate 35 is fixedly installed with the sleeve 41, and the top of the expansion column 7 is slidably inserted inside the sleeve 41. Guide grooves 8 connected to the interior of the sleeve 41 are provided on both sides of the bottom end. The top of the side wall of the expansion column 7 is fixedly installed with a positioning block 42 extending into the guide groove 8, and the positioning block 42 is slidably connected to the guide groove 8. The side wall of the expansion column 7 away from the positioning block 42 is symmetrically provided with a through hole 9 penetrating the sleeve 41. The fixing rod 43 is slidably inserted inside the through hole 9. One end of the fixing rod 43 penetrates the through hole 9 and extends to the outside of the sleeve 41 and is welded with a stopper 45. A first spring 44 sleeved on the surface of the fixing rod 43 is fixedly installed between the stopper 45 and the side wall of the sleeve 41.

[0023] During use, the operator first pulls the stopper 45 to drive the fixing rod 43 to move toward the side away from the sleeve 41. While pulling the stopper 45, the first spring 44 is stretched and deformed. Then, the bottom end of the reaming column 7 is held, and the positioning block 42 at its top is placed in the corresponding guide groove 8. The top of the reaming column 7 is then slid into the sleeve 41. When the top of the reaming column 7 enters the sleeve 41, the reaming column 7 is rotated so that the positioning block 42 reaches the deep inside of the guide groove 8 along the opening trajectory of the guide groove 8. Then, the force applied to the stopper 45 is released. At this time, the first spring 44 is reset and deformed, so that the fixing rod 43 is slidably inserted into the corresponding through hole 9 through the stopper 45, so that the reaming column 7 can be fixed so that it will not shake during subsequent reaming operations. The installation is simple, and the operator can quickly disassemble and install the reaming column 7 according to the needs of reaming holes of different diameters in actual use.

[0024] A resistance spring 10 is welded to the top surface of the inner wall of the sleeve 41, and the other end of the resistance spring 10 is welded to the top surface of the resistance plate 11. The bottom surface of the resistance plate 11 contacts the top end of the hole expansion column 7, and the resistance plate 11 is slidably connected to the inner wall of the sleeve 41. When the hole expansion column 7 is slidably inserted into the sleeve 41, the top end of the hole expansion column 7 applies an extrusion force to the resistance plate 11, and at the same time, the resistance spring 10 is compressed and deformed under the action of the extrusion force, and then rebounds through the elasticity of the resistance spring 10 itself, so that the bottom surface of the resistance plate 11 can be tightly pressed against the top end of the hole expansion column 7, and then the hole expansion column 7 can make the positioning block 42 firmly in the guide groove 8, thereby further increasing the stability of the hole expansion column 7 after installation.

[0025] The side of the hole-expanding column 7 is provided with a fixing component located on the bottom surface of the support plate 35 for pressing and fixing the rubber part when expanding the hole. The fixing component includes a support rod 51, a connecting rod 52, a fixing plate 53 and a second spring 54. The bottom surface of the support plate 35 is welded with a support rod 51 located on the side of the hole-expanding column 7, and the inside of the support rod 51 is slidably connected with the connecting rod 52. One end of the connecting rod 52 passes through the bottom end of the support rod 51 and is welded to the top surface of the fixing plate 53. A second spring 54 sleeved on the surface of the connecting rod 52 is fixedly installed on the top surface of the fixing plate 53, and the other end of the second spring 54 is fixedly installed on the bottom end of the support rod 51. Three support rods 51 are provided and distributed in an equilateral triangle on the bottom surface of the support plate 35. The bottom surface of the fixing plate 53 is bonded with an anti-slip pad for increasing the stability of the rubber part when the fixing plate 53 is pressed and fixed.

[0026] During use, when the reaming column 7 is lowered for reaming operation through the support plate 35 driven by the lifting rod 34, the bottom surface of the fixing plate 53 first contacts the top surface of the rubber part, thereby pressing and fixing the rubber part. During the continuous descending process of the support plate 35, the end of the connecting rod 52 away from the fixing plate 53 slides toward the inside of the support rod 51, and at the same time, the second spring 54 is compressed and deformed, thereby not only enabling the fixing plate 53 to press and fix the rubber part during reaming, but also not affecting the normal reaming operation of the reaming column 7.

[0027] Working principle: First, it is necessary to select an appropriate reaming column 7 according to the needs of reaming, and then pull the stopper 45 to drive the fixing rod 43 to move toward the side away from the sleeve 41, and at the same time, the first spring 44 is stretched, and the reaming column 7 is held to place the positioning block 42 in the guide groove 8, and then the top of the reaming column 7 is inserted into the sleeve 41, and the reaming column 7 is rotated so that the positioning block 42 reaches the deep inside of the guide groove 8 along the opening trajectory of the guide groove 8. When the reaming column 7 is inserted into the sleeve 41, its top end applies an extrusion force to the contact plate 11, and at the same time, through the elastic rebound of the contact spring 10 itself, the contact plate 11 can tightly press the top of the reaming column 7, and then release the force applied to the stopper 45, and the elastic rebound of the first spring 44 makes the fixing rod 43 43 is slidably inserted into the corresponding through hole 9, so that the expansion column 7 and the sleeve 41 can be fixed, and then the rubber part is placed above the expansion groove 6, and the motor 31 is started to control the operation of the driving assembly. When the moving blocks 33 move closer to each other, the supporting plate 35 is moved downward by the lifting rod 34, so that the expansion column 7 can synchronously move downward to expand the hole. The bottom surface of the fixing plate 53 first contacts the rubber part and presses it to fix it. At this time, the expansion column 7 continues to move downward, so that one end of the connecting rod 52 slides toward the inside of the support rod 51, and the second spring 54 is compressed, which not only enables the fixing plate 53 to press and fix the rubber part, but also does not affect the downward expansion of the expansion column 7.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
