Connection structure and rollgang

Technical Field

The invention relates to the technical field of heating furnaces, in particular to a connecting structure and a conveying roller way.

Background

Thermoforming technology is one of the main stream directions of automobile lightweight technology, and is increasingly widely applied to the manufacturing industry of automobile body parts of passenger automobiles.

The key equipment of the thermoforming production line is a roller hearth type heating furnace, which is mainly used for heating and conveying the material sheets and completely austenitizing the material sheets. The roller hearth type heating furnace generally comprises a feeding platform, a furnace body, a ceramic roller way in the furnace, a driving system, a discharging platform, a heating system, an electric control system and the like. The roller hearth type heating furnace mainly uses a solid ceramic roller and a hollow ceramic roller, steel shaft sleeves are arranged at two ends of the ceramic roller, are supported by bearings and are connected with a driving system to carry out tablet conveying work.

The furnace roller path of the roller hearth type heating furnace for thermoforming mainly adopts a ceramic roller way, and after equipment runs for a period of time, roller breakage often occurs due to corrosion and nodulation or other accidents of the ceramic roller way, and even though the number of roller breakage of each line of foreign production lines is about 200 (about 300 in the furnace in total). The hollow roller is used for heating the area, and keeps running at a slow speed all the time. The solid roll bar is used for the furnace outlet, and is required to be frequently (3-4 times per minute) changed from low speed of 100mm/s to 2000mm/s and then changed to 100mm/s for repeated operation due to process requirements. This puts higher demands on the connection tightness of the shaft sleeves at the two ends of the roller rod, and the roller rod cannot slip or loosen. At present, a steel shaft sleeve of a solid roller and a shaft head of a ceramic roller are mechanically locked by a glue injection or pin penetrating mode, and an iron head and ceramic are integrated and cannot be reused, so that certain waste is caused. The hollow roller adopts a hot-charging mode to mount the shaft sleeve on the ceramic shaft head, but a user cannot hot-charge on site, and only can complete set of repeated purchase, and cannot be reused.

Next, a detailed description will be given of the specific structure of the connecting structure 10 and the conveying roller table in the embodiment of the present application with reference to the accompanying drawings.

As shown in fig. 1 to 6, the connection structure 10 in the embodiment of the present application is used for installing a ceramic roller, and includes a shaft sleeve 100, an expansion sleeve 200 and a locking member 300. The shaft sleeve 100 has a first connection end 110 and a second connection end 120, the first connection end 110 is barrel-shaped, the end of the ceramic roller rod can extend into the first connection end 110, the second connection end 120 is coaxially arranged with the first connection end 110, and the second connection end 120 can be connected with a driving system. The expansion sleeve 200 has a first adjusting end 210 and a second adjusting end 220, the first adjusting end 210 and the second adjusting end 220 are wound around and close to each other along the circumferential direction to form a cylinder shape, and the expansion sleeve 200 is disposed in the first connecting end 110 and is located between the outer circumferential surface of the end portion of the ceramic roller and the inner circumferential surface of the first connecting end 110. The locking member 300 is disposed between the inner circumferential surface of the first coupling end 110 and the expansion sleeve 200 for adjusting the distance between the first adjusting end 210 and the second adjusting end 220.

From the above, the distance between the first adjusting end 210 and the second adjusting end 220 of the expansion sleeve 200 can be adjusted through the locking piece 300, so that the expansion sleeve 200 can wrap and lock the end part of the ceramic roller, and the ceramic roller is fixed through the friction force between the expansion sleeve 200 and the ceramic roller. The distance between the first adjusting end 210 and the second adjusting end 220 can be adjusted, so that the pressure between the expansion sleeve 200 and the end part of the ceramic roller rod can be adjusted, and the friction force between the expansion sleeve 200 and the ceramic roller rod can be further adjusted, so that the firmness of the ceramic roller rod can be adjusted.

In addition, when the ceramic roller is mounted, the end portion of the ceramic roller may be inserted into the first connection end 110, so that the expansion sleeve 200 is sleeved on the ceramic roller. The distance between the first adjusting end 210 and the second adjusting end 220 of the expansion sleeve 200 is adjusted through the locking piece 300, so that the radius of the expansion sleeve 200 is reduced, the expansion sleeve 200 is tightly held and fixed with the ceramic roller, and the ceramic roller is installed. When the ceramic roller needs to be disassembled, the distance between the first adjusting end 210 and the second adjusting end 220 of the expansion sleeve 200 can be adjusted through the locking piece 300, so that the radius of the expansion sleeve 200 is increased, the expansion sleeve 200 and the ceramic roller are loosened, the end part of the ceramic roller can be pulled out from the first connecting end 110, and the ceramic roller is disassembled. Therefore, the ceramic roller can be more conveniently installed and detached, and the connection structure 10 does not need to be replaced when the ceramic roller is replaced, so that the connection structure 10 can be reused.

In some embodiments, the expansion sleeve 200 may be cylindrical, as shown in fig. 5, and a notch 230 is axially provided on the expansion sleeve 200 to disconnect the expansion sleeve 200 in the circumferential direction, so that the expansion sleeve 200 forms a first adjustment end 210 and a second adjustment end 220 at the position of the notch 230. The notch 230 provides a moving space for the first adjustment end 210 and the second adjustment end 220, and the first adjustment end 210 and the second adjustment end 220 are close to each other, so that the radius of the expansion sleeve 200 can be reduced, and the first adjustment end 210 and the second adjustment end 220 are far away from each other, so that the radius of the expansion sleeve 200 can be increased.

In some embodiments, the first adjustment end 210 and the second adjustment end 220 may also be radially offset. The first adjustment end 210 is adjacent to the second adjustment end 220 such that the radius of the tension sleeve 200 may be increased, and the first adjustment end 210 is spaced away from the second adjustment end 220 such that the radius of the tension sleeve 200 may be decreased. This is not a limitation.

As shown in fig. 3, 5 and 6, the first adjustment surface 240 is provided on the outer circumferential surface of the expansion sleeve 200, and the first adjustment surface 240 is inclined in the axial direction of the expansion sleeve 200. The locking member 300 is located between the inner surface of the first connecting end 110 and the expansion sleeve 200, and a second adjusting surface 310 is disposed on a side of the locking member 300 corresponding to the first adjusting surface 240, where the second adjusting surface 310 is attached to the first adjusting surface 240. Thus, by the first adjusting surface 240 being engaged with the second adjusting surface 310, after the position of the locking member 300 is adjusted, the first adjusting surface 240 and the second adjusting surface 310 can slide, so that the expansion sleeve 200 can be pushed to deform in the radial direction. Therefore, the distance between the first adjusting end 210 and the second adjusting end 220 can be changed, the radius of the expansion sleeve 200 can be adjusted, and the tightness between the expansion sleeve 200 and the ceramic roller rod can be further changed. In addition, when the radius of the locking member 300 pushing the expansion sleeve 200 is reduced, the locking member 300 receives a reaction force in a direction away from the axis when the expansion sleeve 200 is locked with the ceramic roller, so that the pressure between the locking member 300 and the inner surface of the first connecting end 110 is increased, and the friction force between the locking member 300 and the first connecting end 110 is increased. Thereby, the fixation between the expansion shell 200 and the sleeve 100 can be achieved.

As shown in fig. 2 and 3, the connection structure 10 further includes a connection member 400, where the connection member 400 is disposed on the sleeve 100, and drives the locking member 300 to move along the axial direction of the expansion sleeve 200. Therefore, the locking piece 300 can be driven to move along the axial direction of the expansion sleeve 200 through the connecting piece 400, so that the first adjusting surface 240 and the second adjusting surface 310 slide to adjust the tightness between the expansion sleeve 200 and the ceramic roller.

In some embodiments, the connecting piece 400 may be, for example, shown in fig. 2 and 3, and a bolt, where a screw of the bolt is inserted through the first connecting end 110, and the bolt is disposed along the axial direction of the expansion sleeve 200 and is in threaded connection with the locking piece 300. Specifically, for example, as shown in fig. 2 and 3, a plurality of through holes 111 are uniformly formed at the bottom of the first connecting end 110, the through holes 111 are disposed along the axial direction of the first connecting end 110, and the screw of the bolt may pass through the through holes 111 to be screwed with the locking member 300 at the opening position of the first connecting end 110. Alternatively, the through hole may be disposed at an opening position of the first connecting end 110, the screw of the bolt is in threaded connection with the through hole, the end of the screw abuts against the locking member 300, and the locking member 300 can be pushed to move toward the bottom of the first connecting end 110 by rotating the bolt. Therefore, the locking piece 300 can be driven to move along the axis of the expansion sleeve 200 by rotating the bolt, so that the tightness between the expansion sleeve 200 and the ceramic roller rod is adjusted. Meanwhile, the locking member 300 may be fixed to the sleeve 100 through the connection member 400, thereby improving the firmness between the expansion shell 200 and the first connection end 110.

As shown in fig. 3 to 5, a third adjusting surface 250 is further disposed on the outer circumferential surface of the expansion sleeve 200, and the third adjusting surface 250 is disposed obliquely in the axial direction of the expansion sleeve 200. The inner circumferential surface of the first connecting end 110 is provided with a fourth adjusting surface 112, and the fourth adjusting surface 112 is attached to the third adjusting surface 250. Thus, by adjusting the position of the expansion shell 200 within the first connection end 110, the third adjustment surface 250 and the fourth adjustment surface 112 can be slid relative to each other. The expansion sleeve 200 can be deformed in the radial direction, so that the tightness between the expansion sleeve 200 and the ceramic roller rod can be adjusted. In addition, by arranging the third adjusting surface 250 and the fourth adjusting surface 112, the position for driving the expansion sleeve 200 to deform can be increased, so that the deformation of the expansion sleeve 200 is more uniform, and the connection between the expansion sleeve 200 and the ceramic roller is more stable and firm.

Further, as shown in fig. 3-6, the first adjustment surface 240 is inclined in the opposite direction to the third adjustment surface 250. By reversing the direction of inclination of the first adjustment surface 240 and the third adjustment surface 250, the direction of the first adjustment surface 240 and the second adjustment surface 310 in the axial direction of the expansion sleeve 200 can be reversed from the direction of the third adjustment surface 250 and the fourth adjustment surface 112 in the axial direction of the expansion sleeve 200. Thus, the force applied to the tension sleeve 200 in the axial direction can be reduced, and the tension sleeve 200 can be more stable.

As shown in fig. 3, the locking member 300 is located near the opening of the first connecting end 110, and the fourth adjusting surface 112 is located near the bottom of the first connecting end 110. Therefore, the locking piece 300 is arranged at the position, close to the opening, of the first connecting end 110, and the fourth adjusting surface 112 is arranged at the position, close to the bottom, of the first connecting end 110, so that the expansion sleeve 200 can be driven to deform at the two end positions of the expansion sleeve 200, and the radius of the expansion sleeve 200 can be adjusted. Thus, the fastening connection between the expansion sleeve 200 and the ceramic roller rod can be more stable.

As shown in fig. 3, the second adjustment surface 310 is inclined toward the bottom of the first connection end 110, and the fourth adjustment surface 112 is inclined toward the opening of the first connection end 110. Therefore, by inclining the second adjusting surface 310 towards the bottom direction of the first connecting end 110, the force of the first adjusting surface 240 and the second adjusting surface 310 in the axial direction of the expansion sleeve 200 can drive the expansion sleeve 200 to move towards the inside of the first connecting end 110, so that the expansion sleeve 200 is prevented from being separated from the first connecting end 110, and the running stability of equipment is improved. In addition, the locking member 300 moves towards the bottom of the first connecting end 110, and can also push the expansion sleeve 200 to move towards the bottom of the first connecting end 110, so that the third adjusting surface 250 and the fourth adjusting surface 112 slide, push the expansion sleeve 200 to move towards the axial direction, reduce the radius of the expansion sleeve 200, and make the connection between the expansion sleeve 200 and the ceramic roller more firm.

As shown in fig. 6, the locking member 300 is an annular member, and the first adjustment surface 240. Thus, by providing the locking member 300 as an annular member, the second adjustment surface 310 can be provided along the circumferential direction of the expansion shell 200, and the second adjustment surface 310 can be abutted against the first adjustment surface 240 along the circumferential direction of the expansion shell 200. Thereby, the contact area of the first adjustment surface 240 and the second adjustment surface 310 can be increased, thereby increasing the stability between the first adjustment surface 240 and the second adjustment surface 310.

In some embodiments, the locking member may also be, for example, a clip structure that adjusts the radius of the expansion sleeve 200 by fitting the clip structure over the outer circumference of the expansion sleeve 200, thereby adjusting the firmness between the expansion sleeve 200 and the ceramic roller.

In some embodiments, the connecting member may be an annular member, the outer circumferential surface of the connecting member is in threaded connection with the inner circumferential surface of the first connecting end 110, the bottom side surface of the connecting member facing the first connecting end 110 abuts against the locking member 300, and the locking member 300 may be pushed to move along the axial direction of the expansion sleeve 200 by rotating the connecting member 400.

Alternatively, in some embodiments, the connecting piece 400 may be omitted, the outer peripheral surface of the locking piece is screwed with the inner peripheral surface of the first connecting end 110, and the locking piece is rotated to adjust the position of the locking piece in the first connecting end 110, so that the second adjusting surface 310 slides with the first adjusting surface 240 to adjust the radius of the expansion sleeve 200, and the firmness between the expansion sleeve 200 and the ceramic roller rod is adjusted.
