Description

Technical Field

[0001] The utility model relates to the field of transmission chains, in particular to a heavy truck assembly production line chain with guide wheels. Background Art

[0002] Conveyor chain is a common mechanical transmission and conveying component, usually made of metal material, consisting of alternately connected inner chain links and outer chain links.

[0003] At present, the inner chain link structure includes a pair of inner attached plates, a sleeve for connecting the inner attached plates and a roller sleeved on the outside of the sleeve, and the outer chain link structure includes a pair of outer attached plates, a pin for connecting the outer attached plates and rollers connected to both ends of the pin. The inner chain link and the outer chain link are connected by sleeves on the pin. When the conveyor chain of this structure is in use: 1. Impurities are easy to fall between the pin, the sleeve and the attached plate, affecting the relative rotation between the pin, the sleeve and the attached plate. In some large-scale automobile assembly line conveying equipment occasions in China, the conveyor chain of this structure cannot adapt to heavy-weight transportation tasks such as heavy trucks. After use, the chain is severely worn and the service life is not long; 2. The chain is prone to serpentine travel during the transmission process and cannot run in the center. At the same time, due to the complex layout of the automobile production line, the chain is difficult to replace, which affects the production of the production line and cannot meet the needs of customers for continuous use. Therefore, the existing conveyor chain structure for heavy-weight transportation tasks such as heavy trucks needs to be further improved. Utility Model Content

[0028] Combination Figures 1 to 4 The utility model of the heavy truck assembly production line chain with guide wheels is further described.

[0029] A heavy truck assembly production line chain with guide wheels is characterized in that it comprises an inner link 2 and an outer link 1 connected in sequence, a shielding plate 4 is provided on the top of each of the inner link 2 and the outer link 1, and guide wheel assemblies 3 are provided on the left and right sides of the inner link 2.

[0030] Specifically, in the structure of the outer link 1, each outer link 1 includes an outer plate group, a pin 12 and a roller 13. The outer plate group includes two parallel outer plates 111 on the left and right. There are two pins 12, which are connected between the two outer plates 111 in the front and back distribution. Both ends of each pin 12 pass through the outer plate 111 and are located on the outside of the outer plate 111, and are connected to a bearing 15, and the corresponding roller 13 is installed on the bearing 15. The shielding plate 4 on the outer link 1 is welded and set on the top of the two outer plates 111 at the same time, shielding the space between the two outer plates 111 and fixing the two outer plates 111 at the same time.

[0031] The pin 12 is located outside the outer plate 111 and has an outer mounting step at the outer end for the bearing 15 to be mounted. The bearing 15 is sleeved on the outer end of the pin 12, and then the inner ring of the bearing 15 is pressed against the outer mounting step through the shaft elastic circlip 16 to fix the bearing 15 on the pin 12. The roller 13 has an inner mounting step in the mounting hole for assembling with the bearing 15, and the inner side of the outer ring of the bearing 15 abuts against the inner side of the outer ring of the bearing 15. The mounting hole is provided with a dust cover 17 at a position corresponding to the outer side of the bearing 15, and a hole elastic circlip 18 is provided on the outer side of the dust cover 17. The hole elastic circlip 18 can press the dust cover 17 against the outer ring of the bearing 15, and fix the bearing 15 and the dust cover 17 at the same time.

[0032] The outer plate assembly and the pin shaft 12 are axially fixed via a clamping plate 14 .

[0033] The diameter of the roller 13 gradually decreases from the middle position to the outer end position in the axial direction, forming a guide section 131. During use, the bottom wall of the channel steel guide rail 6 is matched with the guide section 131 to set an inclined section 61, and the high end of the inclined section 61 gradually decreases from the inside to the outside. Under this structure, the roller 13 can automatically deviate outward when rolling in the channel steel guide rail 6, that is, the left roller 13 automatically deviates to the right, and the right roller 13 automatically deviates to the left. Therefore, when the rollers 13 on the left and right sides are symmetrically offset, the entire outer chain link 1 can roll in a straight line in the center of the channel steel guide rail 6, significantly reducing the problem of collision between the chain and the inner wall of the channel steel guide rail 6.

[0034] In the structure of the inner chain link 2, the inner chain link 2 includes an inner plate group, a sleeve 22 and a roller 23. The inner plate group includes two parallel inner plates 21 on the left and right, and the two inner plates 21 are located on the inner side of the two outer plates 111. The shielding plate 4 on the inner chain link 2 is welded and set on the top of the two inner plates 21 to shield the space between the two inner plates 21 and fix the two inner plates 21. There are two sleeves 22, which are distributed front and back and connected between the two inner plates 21. The adjacent inner chain links 2 and the outer chain links 1 are connected by sleeves 22 on the pins 12. For example, in the assembly structure of the outer chain link 1 located at the front side and the inner chain link 2 located at the rear side, the sleeve 22 on the front side of the inner chain link 2 is sleeved on the pin 12 on the rear side of the outer chain link 1. The roller 23 is sleeved on the sleeve 22, can rotate relative to the sleeve 22, and cooperate with the sprocket to transmit.

[0035] In the shielding plate 4 structure, an oil hole 41 is provided on the shielding plate 4, and a rubber cover 5 is provided on the oil hole 41. Oil can be easily injected into the inner link 2 and the outer link 1 through the oil hole 41, thereby improving the lubricity of the entire chain and increasing the service life.

[0036] In the guide wheel assembly 3, each set of guide wheel assembly 3 includes two upper and lower parallel guide attachment plates 31 installed on the outer side wall of the inner attachment plate 21 and a guide wheel 32 arranged between the two guide attachment plates 31. When the chain deviates while running in the channel steel guide rail 6, the guide wheel 32 can first contact with the inner side wall of the channel steel guide rail 6 to generate rolling friction, thereby achieving a guiding effect, preventing the entire chain from deviating or getting stuck, and improving the stability of chain transmission.
