Description

Technical Field

[0001] The invention belongs to the technical field of glass production equipment and relates to a riveting device for a supporting block on a glass conveyor chain. Background Art

[0002] The glass conveyor chain used for vertical glass transportation is composed of two conveyor chains. A support block is fixedly arranged on the rotating pin of the conveyor chain. Since the retaining edge on the support block that limits the side of the glass is a rubber part (to avoid wear on the glass), the support block is composed of two parts: a clip and a rubber sheet. When making the conveyor chain, the rubber sheet needs to be riveted to the clip. At the same time, since the rubber sheet is severely worn, it needs to be replaced regularly. Therefore, the equipment for riveting the glass conveyor chain is frequently used. Traditional manual riveting is not only inefficient, but also prone to safety accidents such as hand crushing. Summary of the invention

[0003] The purpose of the present invention is to provide a riveting device for supporting blocks on a glass conveyor chain in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to improve the safety and efficiency of riveting.

[0004] The object of the present invention can be achieved by the following technical solutions: a riveting device for a support block on a glass conveyor chain, characterized in that the glass conveyor chain includes a closed chain composed of a plurality of chain links, the closed chain is provided with a plurality of support assemblies, the support assemblies include a clip fixed on a rotating pin of the chain link and a rubber sheet fixed on the clip, the rubber sheet includes an insertion section and a limit strip located at the outer end of the insertion section, the clip includes two clamping plates, the insertion section is fixed between the two clamping plates by at least two rivets, the riveting device includes a frame, an upper pressing mechanism, a lower pressing mechanism The mechanism and two sprockets respectively located at two ends of the frame, the upper pressure mechanism includes a hydraulic cylinder and an upper pressure head fixed on the hydraulic cylinder push rod, the lower pressure mechanism includes a mounting block fixed on the frame, a lower pressure rod longitudinally slidably connected to the mounting block, a driving shaft rotatably connected to the mounting block and a reduction motor capable of driving the driving shaft to rotate, the lower pressure rod is provided with a longitudinally arranged rack, the driving shaft is provided with an outer gear ring meshing with the rack, the upper pressure head and the lower pressure rod are in the same straight line, and the rivet on the closed chain pulled by the two sprockets can be located between the upper pressure head and the lower pressure rod.

[0005] Furthermore, the insertion section has an insertion hole corresponding to the rivet one by one, the inner wall of the insertion hole has a limiting convex ring, and the rivet has a limiting ring groove corresponding to the limiting convex ring.

[0006] Furthermore, the outer side surface of the clamping plate away from the limiting strip has a guide groove, and the mounting block has a guide convex strip adapted to the guide groove.

[0007] Furthermore, the sprocket is driven by a servo motor.

[0008] Furthermore, the frame includes a carrier plate and an avoidance channel located below the carrier plate, and the two straight sections of the closed chain are respectively located above the carrier plate and in the avoidance channel.

[0009] Furthermore, the pressing rod can partially extend out of the side surface of the guiding protrusion, and the side surface of the guiding protrusion has a positioning opening.

[0010] Furthermore, the side surface of the limiting strip close to the rivet has an alignment opening adapted to the pressing rod.

[0011] Furthermore, the end of the guide convex strip has a guide inclined surface.

[0012] The two closed chains are symmetrically distributed, and the area between the two limit bars is the limit area of ​​the glass end face. The glass conveying equipment is also provided with a wheel structure for driving the edge banding chain to rotate and a support rail cooperating with the guide groove. It can be seen that the support assembly does not participate in the transmission of the edge banding chain and is only used to support the glass. Therefore, the riveting strength requirements of the clamping plate and the rubber sheet are relatively low, the rivets can be made of relatively soft metal, and the requirements for the action strength of the upper and lower pressing mechanisms are also relatively low.

[0013] The sprockets driven by two servo motors drive the closed chain to rotate. The two straight sections of the closed chain are respectively located at the upper and lower ends of the carrier plate to ensure the smooth operation of the two closed sections. The rubber sheet on the closed chain that has not been riveted can be reliably connected to the clamping sheet. This is because the inner wall of the socket has a limiting convex ring. The rubber sheet is made of rubber and has a certain elasticity. The rivet has a limiting ring groove corresponding to the limiting convex ring. The rivet is manually inserted into the corresponding socket. Under the action of the limiting ring groove and the limiting convex ring, the rivet will not be separated from the rubber sheet, and the rubber sheet can also be connected to the two clamping plates.

[0014] During riveting, the servo motor drives the closed chain to run. When the rivet is located between the upper pressure head and the lower pressure rod, the upper pressure head and the lower pressure rod move towards each other, causing the two ends of the rivet to be squeezed and expanded, thereby fixing the clamping plate and the rubber sheet.

[0015] When the rivet has not reached between the upper pressure head and the lower pressure rod, the outer gear ring on the drive shaft engages with the rack on the lower pressure rod to retract the lower pressure rod. The upper pressure head also retracts under the action of the hydraulic cylinder. The lower end of the rivet can smoothly reach the position of the lower pressure rod under the action of the guiding inclined surface, that is, reach the positioning port. At this time, the closed chain will encounter greater resistance if it continues to move. This moment is the riveting moment, and aligning the port can improve the accuracy of riveting.

[0016] With this equipment, the operator can perform riveting by observation without manual alignment of rivets or control of closed chains, which greatly improves the safety of operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0028] like Figure 2-6As shown, the glass conveyor chain includes a closed chain composed of a plurality of chain links 1, and a plurality of supporting components are arranged on the closed chain. The supporting components include a clip fixed on the rotating pin of the chain link 1 and a rubber sheet fixed on the clip. The rubber sheet includes an insertion section 21 and a limit strip 22 located at the outer end of the insertion section 21. The clip includes two clamping plates 23. The insertion section 21 is fixed between the two clamping plates 23 by at least two rivets 24. Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, the riveting equipment includes a frame 3, an upper pressing mechanism, a lower pressing mechanism and two sprockets 31 respectively located at both ends of the frame 3, the upper pressing mechanism includes a hydraulic cylinder 32 and an upper pressing head 33 fixed on the push rod of the hydraulic cylinder 32, the lower pressing mechanism includes a mounting block 34 fixed on the frame 3, a lower pressing rod 35 longitudinally slidably connected to the mounting block 34, a driving shaft 36 rotatably connected to the mounting block 34 and a reduction motor 37 capable of driving the driving shaft 36 to rotate, the lower pressing rod 35 is provided with a longitudinally arranged rack, the driving shaft 36 is provided with an outer gear ring 38 meshing with the rack, the upper pressing head 33 and the lower pressing rod 35 are in the same straight line, and the rivet 24 on the closed chain pulled by the two sprockets 31 can be located between the upper pressing head 33 and the lower pressing rod 35.

[0029] The inserting section 21 has an inserting hole corresponding to the rivet 24 one by one, the inner wall of the inserting hole has a limiting protruding ring 41 , and the rivet 24 has a limiting ring groove 42 corresponding to the limiting protruding ring 41 .

[0030] The outer side surface of the clamping plate 23 away from the limiting strip 22 has a guide groove 51 , and the mounting block 34 has a guide convex strip 52 matched with the guide groove 51 .

[0031] The sprocket 31 is driven by a servomotor 53 .

[0032] The frame 3 includes a carrier plate 54 and an escape passage 55 located below the carrier plate 54 , and two straight sections of the closed chain are located above the carrier plate 54 and in the escape passage 55 , respectively.

[0033] The pressing rod 35 can partially extend out of the side surface of the guiding protrusion 52 . The side surface of the guiding protrusion 52 has a positioning opening 61 .

[0034] The side surface of the limiting strip 22 close to the rivet 24 has an alignment opening 62 adapted to the pressing rod 35 .

[0035] The end of the guide ridge 52 has a guide slope 63 .

[0036] The two closed chains are symmetrically distributed, and the area between the two limit strips 22 is the limit area of ​​the glass end face. The glass conveying equipment is also provided with a wheel structure for driving the edge banding chain to rotate and a support rail cooperating with the guide groove 51. It can be seen that the support assembly does not participate in the transmission of the edge banding chain and is only used to support the glass. Therefore, the riveting strength requirements of the clamping plate 23 and the rubber sheet are relatively low. The rivet 24 can be a relatively soft metal, and the requirements for the strength of the upper and lower pressing mechanisms are also relatively low.

[0037] The sprocket 31 driven by the two servo motors 53 drives the closed chain to rotate. The two straight sections of the closed chain are respectively located at the upper and lower ends of the carrier plate 54, ensuring the smooth operation of the two closed chains. The rubber sheet on the unriveted closed chain can be reliably connected to the clamping sheet. This is because the inner wall of the socket has a limiting convex ring 41. The rubber sheet is made of rubber and has a certain elasticity. The rivet 24 has a limiting ring groove 42 corresponding to the limiting convex ring 41. The rivet 24 is manually inserted into the corresponding socket. Under the action of the limiting ring groove 42 and the limiting convex ring 41, the rivet 24 will not be separated from the rubber sheet, and the rubber sheet can also be connected to the two clamping plates 23.

[0038] During riveting, the servo motor 53 drives the closed chain to run. When the rivet 24 is located between the upper pressure head 33 and the lower pressure rod 35, the upper pressure head 33 and the lower pressure rod 35 move toward each other, causing the two ends of the rivet 24 to be squeezed and expanded, thereby fixing the clamping plate 23 and the rubber sheet.

[0039] When the rivet 24 has not reached between the upper pressure head 33 and the lower pressure rod 35, the outer gear ring 38 on the drive shaft 36 engages with the rack on the lower pressure rod 35, causing the lower pressure rod 35 to retract, and the upper pressure head 33 also retracts under the action of the hydraulic cylinder 32. The lower end of the rivet 24 can smoothly reach the position of the lower pressure rod 35 under the action of the guide slope 63, that is, reach the positioning port 61. At this time, the closed chain will encounter greater resistance if it continues to move. This moment is the riveting moment, and aligning the port 62 can improve the riveting accuracy.

[0040] Through the device, the operator can realize riveting by observation without manual alignment of the rivets 24 or control of the closed chain, which greatly improves the safety of the operation.

[0041] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
