Description

Technical Field

[0001] The present invention relates to the field of chain production, and in particular to an intelligent chain assembly machine. Background Art

[0048] Combine Figures 1 to 11 The chain intelligent assembly machine of the present invention is further described.

[0049] A chain intelligent assembly machine is characterized by comprising a frame 10 and a chain guide rail 2 arranged on a table 101 of the frame 10 and extending left and right.

[0050] The chain guide 2 has a first assembly position 24 , a second assembly position 25 , a third assembly position 26 , a fourth assembly position 27 and a fifth assembly position 28 , which are distributed in the extension direction, ie, from left to right.

[0051] The frame 10 is provided with the following components at positions corresponding to the extending direction of the chain guide rail 2:

[0052] The left outer piece feeding mechanism 5, the left single section feeding mechanism 4, the pin feeding mechanism 9 for feeding the material to the first assembly position 24, and the first pressing mechanism 14 for pressing the pin 205 from top to bottom into the left single section 201 and the left outer piece 202;

[0053] The movable piece feeding mechanism 6 for feeding the material to the second assembly position 25 and the second pressing mechanism 15 for initially pressing the movable piece 203 down onto the pin;

[0054] A third pressing mechanism 16 corresponding to the third assembly position 26, pressing the movable plate 203 into place;

[0055] The right single section feeding mechanism 7 for feeding the material to the fourth assembly position 27 and the fourth pressing mechanism 17 for pressing the right single section 204 down onto the pin;

[0056] a right outer sheet feeding mechanism 8 for feeding the material to the fifth assembly position 28 and a fifth pressing mechanism 13 for pressing the right outer sheet 206 down onto the pin;

[0057] The transfer and positioning mechanism 11 sequentially transfers the chain being assembled from the first assembly position 24 to the fifth assembly position 28 and performs positioning.

[0058] Of the aforementioned mechanisms, the first through fifth pressing mechanisms 14, 13 are mounted on a mounting plate 102 above the tabletop 101 of the frame 10, enabling top-down pressing. The left single-section feed mechanism 4 is located at the left end of the chain guide 2. The transfer positioning mechanism 22 and the pin feed mechanism 9 are located at the rear of the chain guide 2. The left outer plate feed mechanism 5, the movable plate feed mechanism 6, the right single-section feed mechanism 7, and the right outer plate feed mechanism 8 are located at the front of the chain guide 2.

[0059] In the chain guide 2 structure, the chain guide 2 has a lower track 21 and an upper track 22. The lower track 21 has a lower slide 211 and a lower support step 212 located above the lower slide 211 and supporting the right piece 2011 in the left single section 201 for transfer. The upper track 22 is superimposed on the lower track 21 and is located on the section of the chain guide 2 corresponding to the fourth assembly position 27 to the exit. It includes an upper slide 221 located above the lower support step 212 and an upper support step 222 located above the upper slide 221 and supporting the right piece 2041 in the right single section 204. When the chain is transferred in the chain guide rail 2, the left outer plate 202 of the chain and the left plate 2012 in the left single section 201 are located in the lower slide 211, the movable plate 203, the right plate 2011 in the left single section 201 and the left plate 2042 in the right single section 204 are located in the upper slide 221, and the right outer plate 206 and the right plate 2041 in the right single section 204 are located above the upper support step 222, thereby realizing stable transfer of the chain.

[0060] In the lower guide rail, the height of the groove bottom 2111 of the lower slide 211 corresponding to the left of the first assembly position 24 is higher than the height of the groove bottom 2112 of the lower slide 211 corresponding to the right of the first assembly position 24. At the same time, an opening 213 for inserting the left outer plate 202 is opened on the front side wall of the lower rail 21 corresponding to the first assembly position 24. The height of this opening 213 is the same as the height of the groove bottom 2112 of the lower slide 211 corresponding to the first assembly position 24 and to the right of the first assembly position 24. The groove bottom portion of the lower slide 211 corresponding to the right of the first assembly position 24 does not include the groove bottom height of the first assembly position 24. This structure is used to insert the left single section 202. Under this structure, the left outer plate 202 can be located below the left single section 201 among the components inserted into the first assembly position 24, facilitating assembly.

[0061] In each feeding mechanism, the left single-section feeding mechanism 4, the left outer plate feeding mechanism 5, the movable plate feeding mechanism 6, the right single-section feeding mechanism 7 and the right outer plate feeding mechanism 8 have the same structure, all including a film barrel 121 and a pushing assembly 122 that pushes the components in the film barrel 121 into the chain guide rail 2.

[0062] The film barrel has a contoured groove 1212 with upper and lower openings, with the upper opening for feeding and the lower opening for discharging. The bottom of the film barrel 121 has a feed channel 1211, located below the lower opening, which receives the lowest components in the contoured groove 1212. A pushing assembly 122 includes a push plate 1221 and a push cylinder 1222 that drives the push plate 1221. The push plate 1221 slides over the feed channel 1211 and corresponds to the lower opening. Driven by the push cylinder 1222, the push plate 1221 pushes the components in the feed channel 1211 out. During the component pushing process, the push plate 1221 blocks the lower opening, preventing the components in the contoured groove from falling. When the push plate is reset and no longer in the component pushing state, it no longer blocks the lower opening, allowing the components in the contoured groove to fall freely, with the components at the lowest position available for the push plate to push.

[0063] The height difference between the feeding channel 1211 and the lower opening of the film roll is smaller than the sum of the heights of the two components in the film roll, so the push plate can only push the component at the bottom of the film roll that falls into the feeding channel 1211 each time.

[0064] Specifically, in the left single-section feeding mechanism 4, the film tube is located at the left end of the lower track 21, and the outlet end of the feeding channel 1211 at the bottom of the film tube is docked with the left end of the lower track 21, so that the pushing cylinder in the pushing assembly drives the pushing plate to move to the right, pushing the left single section 201 into the first assembly position 24 of the lower track 21.

[0065] In the left outer sheet feeding mechanism 5, the outlet end of the feeding channel 1211 at the bottom of the film barrel is docked with the opening 213 on the front side wall of the lower track 21, so that the pushing cylinder drives the pushing plate to push backward, and the left outer sheet 201 in the film barrel can be pushed to the first assembly position 24.

[0066] In the movable plate feeding mechanism 6, the outlet end of the feeding channel 1211 at the bottom of the film tube corresponds to the upper end of the pin shaft on the second assembly position 25, so that the movable plate is pushed out of the feeding channel 1211 and is located at the upper end of the pin shaft for the second pressing mechanism 15 to press down.

[0067] In the right single-section feeding mechanism 7, the outlet end of the feeding channel 1211 at the bottom of the film tube corresponds to the upper end of the pin shaft on the fourth assembly position 27, so that the right single section 204 is pushed out of the feeding channel 1211 and is located at the upper end of the pin shaft for the fourth pressing mechanism 17 to press down.

[0068] In the right outer sheet feeding mechanism 8, the outlet end of the feeding channel 1211 at the bottom of the sheet tube corresponds to the upper end of the pin shaft on the fifth assembly position 28, so that the right outer sheet 206 is pushed out of the feeding channel 1211 and is located at the upper end of the pin shaft for the fifth pressing mechanism 13 to press down.

[0069] In the pin shaft feeding mechanism 9 , the pin shaft feeding mechanism 9 includes a feeding bottom plate 91 , a material discharge seat 94 , a feeding slide plate 92 and a pin shaft feeding driving component 96 .

[0070] The feeding base plate 91 is arranged at the rear side of the first assembly position 24 , and the unloading seat 94 is an inverted U-shaped structure, which is horizontally mounted on the feeding base plate 91 and has two unloading ports 941 distributed on the left and right.

[0071] The feeding slide plate 92 is slidably engaged with the feeding base plate 91 through a sliding module, and has a feeding position and a discharging position. A clamping structure 93 is provided at the front end of the feeding slide plate 92 .

[0072] The feeding pin shaft driving component 96 is a cylinder, which is arranged between the feeding bottom plate 91 and the feeding slide plate 92, and drives the feeding slide plate 92 to switch between the feeding position and the discharging position.

[0073] When the feeding slide 92 moves to the rearmost position driven by the feeding pin shaft driving component, it is in the feeding position. In this state, the clamping structure 93 corresponds to the feeding port. When the feeding pin shaft driving component moves to the frontmost end, it is in the discharging position. The clamping structure 93 corresponds to the first assembly position 24, that is, the clamping structure 93 is located above the first assembly position 24, so that the two pin shafts clamped on the clamping structure 93 are connected with the through holes on the two adjacent left single sections and the two through holes on the left outer piece. After pressing down, they can be inserted into the left single section and the left outer piece.

[0074] The clamping structure 93 includes a clamping block 931 , clamping fingers 932 and an elastic member.

[0075] The clamping block 931 is located at the front end of the feeding slide 92 and is an integral structure with the feeding slide 92 .

[0076] The clamping fingers 932 have two pieces and are distributed on the left and right sides of the clamping block 931. The middle part of each clamping finger 932 is hinged to the lower surface of the feeding slide 92 through a rotating shaft. The front end corresponds to the clamping block 931 and forms a clamping opening 933 for clamping the pin shaft.

[0077] The elastic member is a spring, which is arranged between the feeding slide 92 and the clamping finger 932, that is, one end of the spring rests on the inner side of the rear end of the clamping finger 932, and the other end rests on the bottom of the feeding slide 92, pushing the rear end 9321 of the clamping finger 932 outward, providing a clamping force for the front end of the clamping finger 932 to rotate toward the clamping block 931.

[0078] Furthermore, a partial portion of the outer rear end of the clamping finger 932 is exposed to the outer side of the feeding slide 92 under the push of the spring, and a baffle 95 is provided on the left and right sides of the feeding bottom plate 91 corresponding to the feeding slide 92. The baffle 95 is located along the stroke line of the portion where the rear end of the clamping finger 932 is exposed to the outer side of the feeding slide 92, so that the feeding slide 92 moves from the discharge position to the feed position. The inner wall of the baffle 95 can be pressed against the rear end 9321 of the clamping finger 932, so that the front end of the clamping finger 932 rotates back to the clamping block 931, so that the clamping opening 933 opens, so that the lower end of the pin shaft in the discharge port 941 falls into the clamping opening 933; when the feeding slide 92 is pushed forward, the rear end of the clamping finger 932 can gradually separate from the baffle 95, and the clamping opening 933 gradually clamps the pin shaft.

[0079] In each pressing mechanism, the first pressing mechanism 14, the second pressing mechanism 15, the third pressing mechanism 16, the fourth pressing mechanism 17 and the fifth pressing mechanism 13 all include a driving cylinder installed on the mounting plate 102 of the frame 10 and a pressure block assembly 142 connected to the piston rod of the driving cylinder.

[0080] Specifically, in the first pressing mechanism 14, the driving cylinder is a first oil cylinder 141 invertedly mounted on the upper surface of the mounting plate 102. The pressing block assembly 142 includes a first guide seat 1422 mounted on the lower surface of the mounting plate 102, a first pressing block seat 1421 liftingly engaged in the first guide seat 1422 and connected to the first oil cylinder 141, and a first pressing block 1423 connected to the bottom of the first pressing block seat 1421. The first oil cylinder 141 drives the first pressing block seat 1421 and the first pressing block 1423 to move up and down within the first guide seat 1422. When moving downward, the pin in the clamp 933 is pressed into the left single section and the left outer plate.

[0081] In the second downward pressing mechanism 15, the driving cylinder is a second air cylinder 151 invertedly mounted on the lower surface of the mounting plate 102. The pressure block assembly 142 includes a second pressure block seat 152 mounted on the piston rod of the second air cylinder 151 and a second pressure block 153 mounted on the lower surface of the second pressure block seat 152. The second pressure block 153 has two second guide holes corresponding to the pins on the second assembly position 25. Second guide pins 154 are engaged in a lifting manner in the second guide holes. After the second cylinder 151 drives the second pressure block seat 152 and the second pressure block 153 downward, the movable plate 203 located above the pin on the second assembly position 25 is pressed downward, so that the upper end of the pin is inserted into the two through-holes of the movable plate 203. In this downward pressing structure, the movable plate 203 is pressed downwardly for a relatively shallow stroke. At the same time, the second guide holes and the second guide pins 154 can improve the stability and accuracy of the downward pressing of the movable plate.

[0082] In the third pressing mechanism 16, the driving cylinder is a third cylinder 161 invertedly arranged on the lower surface of the mounting plate 102, and the pressing block assembly 142 includes a third pressing block 162 arranged on the piston rod of the third cylinder 161. After the third cylinder 161 drives the third pressing block 162 to move downward, it can further press the movable plate 203 that has been initially pressed down on the third assembly position 26 into place.

[0083] In the fourth pressing mechanism 17, the driving cylinder is a fourth cylinder 171 invertedly arranged on the lower surface of the mounting plate 102, and the pressing block assembly 142 includes a fourth pressing block 172 arranged on the piston rod of the fourth cylinder 171. After the fourth cylinder 171 drives the fourth pressing block 172 to press down, the right single section 204 located at the upper end of the pin shaft on the fourth assembly position 27 can be pressed down, so that the right single section can be fitted onto the two pin shafts.

[0084] In the fifth downward pressure mechanism 13, the driving cylinder is a fifth oil cylinder 131, which is inverted and mounted on the upper surface of the mounting plate 102. The pressure block assembly 142 includes a fifth guide seat 1321 mounted on the lower surface of the mounting plate 102, a fifth pressure block seat 1322 that is liftably engaged with the fifth guide seat 1321, and a fifth pressure block 1323 mounted on the lower surface of the fifth pressure block seat 1322. The fifth pressure block 1323 has two fifth guide holes corresponding to the two pins on the fifth assembly position 28. The fifth guide holes are engaged by a fifth guide pin 1324 that can be raised and lowered. When the fifth oil cylinder 131 drives the fifth pressure block seat 1322 and the fifth pressure block 1323 downward, it can press down the right outer plate 206 located above the pins on the fifth assembly position 28, allowing the right outer plate to be fitted onto the two pins. The fifth guide holes and the fifth guide pin enhance the stability of the downward pressure on the right outer plate.

[0085] The transfer and positioning mechanism 11 includes a positioning group 111 and a transfer component 112 ; the positioning group 111 includes a moving plate 1117 , a positioning dial plate 1111 and a plurality of component delivery positioning seats.

[0086] The movable plate 1117 is arranged on the table 101 of the frame 10 through a sliding module and can slide along the extension direction of the chain guide 2. The positioning plate 1111 is arranged on the movable plate 1117 through a sliding module, and a longitudinal driving cylinder 1113 is arranged between the positioning plate 1111 and the movable plate 1117, which can drive the positioning plate 1111 to move toward or away from the chain guide 2. The positioning plate 1111 has a positioning tooth 1118 on the side facing the chain guide 2 that can be engaged with the left single section. The component feeding positioning seat is arranged on the positioning plate 1111, and has a component positioning groove 1114 on the front side for positioning the components sent out of the feeding channel 1211. The transfer component 112 is a transverse driving cylinder connected to the movable plate 1117, and drives the movable plate 1117 to slide along the extension direction of the chain guide 2. When transferring the chain, the transverse driving cylinder drives the movable plate 1117 to move to the far left, and the longitudinal driving cylinder 1113 drives the positioning plate 1111 to move forward, so that the multiple positioning teeth 1118 on the front end of the positioning plate 1111 are respectively inserted into the chain link openings 207 of each left single section. The transverse driving cylinder drives the movable plate 1117 to move to the right, which can drive the various chain components in the chain guide 2 to move synchronously to the right by one assembly position, and then the longitudinal driving cylinder 1113 is reset, and the transverse driving cylinder drives the movable plate 1117 to move to the far left again for the next transfer work.

[0087] The positioning groups 111 comprise two groups, arranged along the extension direction of the chain guide 2. Multiple components are fed into the positioning seats and distributed on the movable plates 1117 of the two positioning groups 111. The transverse drive cylinder is a double-acting cylinder, with its piston rods at both ends connected to the two movable plates 1117 via connecting brackets. The two positioning groups 111 are connected to the piston rods at both ends of the transverse drive cylinder via connecting brackets, eliminating installation gaps and ensuring smoother movement.

[0088] The component feeding and positioning seats are respectively the movable piece feeding and positioning seat 1112, the right single section feeding and positioning seat 1115 and the right outer piece feeding and positioning seat 1116. The outlet end of the feeding channel 1211 in the movable piece feeding mechanism 6 corresponds front to back to the component positioning groove 1114 of the movable piece feeding and positioning seat 1112, the outlet end of the feeding channel 1211 in the right single section feeding mechanism 7 corresponds front to back to the component positioning groove 1114 of the right single section feeding and positioning seat 1115, and the outlet end of the feeding channel 1211 in the right outer piece feeding mechanism 8 corresponds front to back to the component positioning groove 1114 of the right outer piece feeding and positioning seat 1116. Therefore, after the movable piece, the right single section and the right outer piece are pushed out of the feeding channel 1211, they will directly enter the component positioning groove 1114 and be accurately positioned, so that the through holes on each component are accurately docked with the pins.

[0089] When assembling,

[0090] The transfer and positioning mechanism 11 transfers the chain in the chain guide 2 from the first assembly position 24 to the fifth assembly position 28 step by step, so that each component is assembled at the corresponding assembly position at the same time;

[0091] The left outer plate feeding mechanism 5, the left single section feeding mechanism 4 and the pin feeding mechanism 9 respectively feed the left outer plate 202, the left single section 201 and the pin 205 to the first assembly position 24, and then the first pressing mechanism 14 presses the lower end of the pin 205 into the left single section 201 and the left outer plate 202;

[0092] The movable plate feeding mechanism 6 delivers the movable plate 203 to the top of the pin of the second assembly position 25, and the second pressing mechanism 15 preliminarily presses the movable plate 203 into the upper end of the pin;

[0093] The third pressing mechanism 16 further presses down the movable plate that has been initially pressed down on the third assembly position 26, so that the movable plate is pressed down into place;

[0094] The right single section feeding mechanism 7 delivers the right single section 204 to above the pin of the fourth assembly position 27, and the fourth pressing mechanism 17 presses the right single section 204 down onto the pin;

[0095] The right outer plate feeding mechanism 8 delivers the right outer plate 206 to above the pin of the fifth assembly position 28, and the fifth pressing mechanism 13 presses the right outer plate 206 down onto the pin to complete the assembly.

[0096] The chain located on the fifth assembly position 28 will automatically move to the right and be sent out of the chain guide 2 under the push of the left chain.
