[0002] In the manufacturing process of mechanical equipment products such as presses, ensuring the stability and durability of the equipment is one of the key elements. Therefore, a machine foot pad is usually installed on the base of the equipment to support the equipment, reduce vibration during equipment operation, and prevent the base of the equipment from being directly contacted with the ground or other hard objects to cause wear.

[0003] In the prior art, a foot pad assembly machine includes a conveying line, a positioning mechanism, an industrial robot hand, at least one foot pad feeder and a clamp. The conveying line is responsible for continuously conveying workpieces such as equipment or equipment base to be assembled. The positioning mechanism accurately stops and fixes the workpieces on the conveying line at the preset assembly position to provide a stable reference for subsequent assembly operations. The foot pad feeder is responsible for outputting foot pads to the feeding position. The clamp, as the execution end of the industrial robot hand, is designed with several movable foot pad chucks, which can simultaneously hold several foot pads and move to the assembly position through the accurate movement of the industrial robot hand to place the several foot pads on the corresponding positions of the base.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] This utility model provides a machine foot pad assembly machine, which addresses the problem of how to simultaneously spirally assemble multiple foot pads 92 onto corresponding positions of workpiece 91.

[0053] See Figure 1 As shown, Figure 1 The figure shown is a perspective view of the machine foot pad assembly machine in the embodiment. The machine foot pad assembly machine includes a frame 1, a workpiece conveying device 2, a spinning device 3, a spinning head 4, and a foot pad conveying device 5.

[0054] The frame 1 is equipped with an assembly station 11.

[0055] The workpiece conveying device 2 is installed on the frame 1 and is used to convey the workpieces 91 to be assembled into the foot pads 92 one by one to the assembly station 11.

[0056] There are at least three spinning heads 4, and each spinning head 4 is set opposite to the foot pad mounting position of the workpiece 91 on the assembly station 11. The spinning head 4 has a limiting groove 41 for accommodating and limiting a single foot pad 92.

[0057] The spinning device 3 is installed on the frame 1 and is in transmission connection with the at least three spinning heads 4. The spinning device 3 is used to drive the spinning heads 4 to rotate and / or to move up and down towards the conveying device, so as to spin or press the at least three foot pads 92 into the corresponding foot pad mounting positions of the workpiece 91 on the assembly station 11.

[0058] The foot pad conveying device 5 is installed on the frame 1 and is used to convey the foot pads 92 into the limiting grooves 41.

[0059] When the machine is used, firstly, the workpiece conveying device 2 conveys the workpiece 91 to be assembled with the foot pads 92 to the assembly station 11, so that the corresponding foot pad mounting positions of the workpiece 91 are one-to-one corresponding to the positions of the spinning heads 4, and at the same time, the foot pad conveying device 5 conveys the foot pads 92 into the at least three limiting grooves 41; then, for the foot pads 92 which need to be assembled by insertion, the spinning device 3 drives the spinning heads 4 to move up and down towards the conveying device, so that the at least three foot pads 92 can be simultaneously pressed into the corresponding foot pad mounting positions of the workpiece 91; for the foot pads 92 which need to be assembled by screwing, the spinning device 3 drives the spinning heads 4 to rotate and move up and down towards the conveying device, so that the at least three foot pads 92 can be simultaneously spun into the corresponding foot pad mounting positions of the workpiece 91; after the foot pads 92 are assembled, the spinning device 3 drives the spinning heads 4 to move up and down away from the conveying device, so as to return to the original position. It can be seen that the machine can not only automatically place or insert multiple foot pads 92 into the corresponding foot pad mounting positions of the workpiece 91 at the same time, but also can automatically screw multiple foot pads 92 into the corresponding foot pad mounting positions of the workpiece 91 at the same time, which effectively improves the production efficiency and expands the application range of the machine.

[0060] The workpiece conveying device 2 can use the existing indexing disc, conveying belt, conveying chain or transplanting mechanism to convey the workpiece 91 to be assembled with the foot pads 92. In the embodiment, the workpiece 91 has four foot pad mounting positions, the number of the spinning heads 4 corresponds to the foot pad mounting positions, and the foot pad conveying device 5 is an indexing disc, and the indexing disc is provided with a letting passage 21 for exposing the foot pad mounting positions of the workpiece 91, so that the spinning device 3 drives the spinning heads 4 to pass through the letting passage 21 to assemble the foot pads 92 on the spinning heads 4 into the corresponding foot pad mounting positions of the workpiece 91.

[0061] Referring to Figure 2 Figure 2 ​For the schematic view of the partial structure of the spinning device, the spinning head and the foot pad conveying device in the embodiment, on the basis of the above embodiment, the groove bottom surface of the limiting groove 41 is inclined and distributed, and at least two annular spaced recesses 411 are opened on the groove bottom surface of the limiting groove 41, so that the friction between the groove bottom surface of the limiting groove 41 and the foot pad 92 in the limiting groove 41 can be improved. In this way, during the process of the spinning head 4 screwing into the corresponding foot pad mounting position of the workpiece 91, the groove bottom surface of the limiting groove 41 can drive the foot pad 92 in the limiting groove 41 to move, so as to screw the foot pad 92 to the workpiece 91, avoiding the situation that the spinning head 4 screws without the foot pad 92 screwing.

[0062] Referring to Figure 2 , Figure 3 and Figure 4 , Figure 3 for the schematic view of the structure of the workpiece conveying device, the spinning device and the spinning head in the first perspective of the embodiment, Figure 4 for the schematic view of the structure of the workpiece conveying device, the spinning device and the spinning head in the second perspective of the embodiment, in one embodiment of the spinning device 3, the spinning device 3 includes a rotating mechanism 31 and a lifting mechanism 32. The rotating mechanism 31 includes a motor 311 and a driving gear 312, and the spinning head 4 includes a driven gear 42. The output shaft of the motor 311 is connected with the driving gear 312 by pin connection, welding or integral connection, etc. The driving gear 312 is engaged with at least three driven gears 42. The motor 311 is used to drive the driving gear 312 to rotate, so as to drive the at least three driven gears 42 to rotate in the same direction. The lifting mechanism 32 is arranged on the rack 1 by screwing or welding, etc. The output end of the lifting mechanism 32 is connected with the motor 311 by screwing or welding, etc. The lifting mechanism 32 is used to drive the rotating mechanism 31 to move up and down. In this way, the spinning device 3 can drive the at least three spinning heads 4 to rotate together through the rotating mechanism 31, and can drive the at least three spinning heads 4 to move up and down towards the conveying device through the lifting mechanism 32. The cooperation of the two can drive the at least three spinning heads 4 to rotate spirally towards the conveying device, so as to adapt to foot pads 92 of different assembly modes and improve the production efficiency.

[0063] The above lifting mechanism 32 can use existing ball screw-nut linear module or linear motor linear module, etc. In this way, the depth position of the different models of foot pads 92 can be controlled.

[0064] Referring to Figure 1 and Figure 2As shown in an embodiment of the spinning device 3, the foot pad conveying device 5 comprises a tray 51, a tray feeding mechanism 52, a foot pad chuck 53 and a foot pad chuck driving mechanism 54. The tray 51 is provided with grooves 511 for accommodating and limiting a single foot pad 92, and the number of the grooves 511 is the same as the number of the foot pads 92 to be installed on the workpiece 91. The tray feeding mechanism 52 is installed on the frame 1 and is used to supply the foot pads 92 to the tray 51. The foot pad chuck 53 corresponds to the grooves 511 one by one and is used to clamp or release the foot pads 92. The foot pad chuck driving mechanism 54 is installed on the frame 1 and is in transmission connection with the foot pad chuck 53. The foot pad chuck driving mechanism 54 is used to drive the foot pad chuck 53 to reciprocate between the tray 51 and the spinning head 4. In this way, when the foot pads 92 are fed, first, the tray feeding mechanism 52 conveys the foot pads 92 into the grooves 511; then, the foot pad chuck driving mechanism 54 drives the foot pad chuck 53 to move to the tray 51, so that the foot pad chuck 53 corresponds to the grooves 511. After the foot pad chuck 53 clamps the foot pads 92 in the corresponding grooves 511, the foot pad chuck driving mechanism 54 drives the foot pad chuck 53 to move to the spinning head 4, so that the foot pad chuck 53 corresponds to the limiting grooves 41. The foot pad chuck 53 releases the foot pads 92 to convey the foot pads 92 into the corresponding limiting grooves 41, so as to complete the feeding of multiple foot pads 92 at the same time, further improving the production efficiency.

[0065] Referring to Figure 2 As shown in an embodiment of the foot pad chuck 53, the foot pad chuck 53 comprises a clamping driving member 531 and at least two annularly spaced clamping arms 532. The clamping arms 532 form a clamping space 533 for clamping the foot pads 92 therebetween. The clamping driving member 531 is arranged on the output end of the foot pad chuck driving mechanism 54 by screwing or welding and is in transmission connection with the at least two clamping arms 532. The clamping driving member 531 is used to drive the at least two clamping arms 532 to approach or move away from each other, so as to reduce or expand the clamping space 533, thereby clamping or releasing the foot pads 92. In this way, when the clamping driving member 531 drives the at least two clamping arms 532 to approach each other, the clamping space 533 is reduced, the foot pads 92 are clamped in the clamping space 533, and the foot pads 92 are clamped and grabbed. When the clamping driving member 531 drives the at least two clamping arms 532 to move away from each other, the clamping space 533 is expanded, and the foot pads 92 are released.

[0066] The above-mentioned clamping driving member 531 can use an existing jaw cylinder, and the output end thereof is connected with the clamping arms 532 by screwing or welding.

[0067] Referring to Figure 2As shown in an embodiment of the foot pad clamp driving mechanism 54, the foot pad clamp driving mechanism 54 comprises a horizontal displacement driving member 541 and a lifting driving member 542. The horizontal displacement driving member 541 is arranged on the rack 1 by screwing or welding, etc., and the output end of the horizontal displacement driving member 541 is connected with the lifting driving member 542 by screwing or welding, etc. Each foot pad clamp 53 is arranged on the output end of the lifting driving member 542 by screwing or welding, etc. In this way, the foot pad clamp driving mechanism 54 can drive all the foot pad clamps 53 to move reciprocally between the tray 51 and the spinning head 4 by the horizontal displacement driving member 541, and drive all the foot pad clamps 53 to move up or down towards the tray 51 or the spinning head 4 by the lifting driving member 542, so as to pick up or place the foot pad 92. It can be seen that the foot pad clamp driving mechanism 54 only needs one horizontal displacement driving member 541 and one lifting driving member 542 to cooperate, so as to realize the conveying of multiple foot pads 92 on the tray 51 into the limiting grooves 41 of the corresponding spinning heads 4, which greatly saves the equipment cost.

[0068] The horizontal displacement driving member 541 and the lifting driving member 542 can use existing ball screw-nut linear module or linear motor linear module, etc.

[0069] Referring to Figure 1 As shown in an embodiment of the tray feeding mechanism 52, the tray feeding mechanism 52 comprises a hopper 521, a vibrating disc 522 and a guide channel 523. The hopper 521 and the vibrating disc 522 are arranged on the rack 1 by screwing or welding, etc. The discharge end of the hopper 521 is communicated with the vibrating disc 522, which is used to provide foot pads 92 in batches for the vibrating disc 522. The discharge end of the vibrating disc 522 is communicated with the feeding end of the guide channel 523, and the vibrating disc 522 is used to convey the foot pads 92 to the guide channel 523 one by one. The foot pad conveying device 5 further comprises a tray driving mechanism 55. The tray driving mechanism 55 is arranged on the rack 1 by screwing or welding, etc., and is in driving connection with the tray 51. The tray driving mechanism 55 is used to drive the tray 51 to rotate, so that each material groove 511 is in turn butted against the discharge end of the guide channel 523. In this way, the tray feeding mechanism 52 can continuously convey the foot pads 92 one by one by the cooperation of the hopper 521, the vibrating disc 522 and the guide channel 523, and can input the foot pads 92 into each material groove 511 one by one by the cooperation of the tray driving mechanism 55, so as to realize the continuous and automatic feeding of the tray 51, which effectively improves the production efficiency; and the tray driving mechanism 55 can also control the one-to-one position of the material groove 511 and the foot pad clamp 53, so that multiple foot pad clamps 53 can simultaneously pick up the foot pads 92 in the corresponding material groove 511.

[0070] The above-mentioned tray driving mechanism 55 can use an existing rotary motor 311 or rotary cylinder, etc. The output end thereof is connected with the tray 51 by screwing or welding, etc.

[0071] Referring to Figure 1 , Figure 3 and Figure 4 , on the basis of any of the above embodiments, the foot pad assembly machine further comprises a pressing mechanism 6. The pressing mechanism 6 is arranged on the frame 1 by screwing or welding, etc., and is opposite to the position of the assembly station 11. The pressing mechanism 6 is used to press the workpiece 91 on the workpiece conveying device 2 against the assembly station 11. In this way, when the foot pad 92 is assembled, the pressing mechanism 6 presses the workpiece 91 against the assembly station 11, which can effectively avoid the influence of the movement of the workpiece 91 on the assembly of the foot pad 92 during the assembly of the foot pad 92, so as to ensure the accurate assembly of the foot pad 92 to the corresponding foot pad mounting position of the workpiece 91.

[0072] The above-mentioned pressing mechanism 6 can use existing telescopic air cylinders or telescopic electric poles, etc. linear displacement driving mechanisms. In this way, the pressing mechanism 6 is elongated, and the workpiece 91 is pressed and limited at the assembly station 11. Conversely, the pressing mechanism 6 is shortened, and the workpiece 91 is released, so that the workpiece conveying device 2 outputs the workpiece 91 with the assembled foot pad 92 from the assembly station 11.

[0073] The above-mentioned spinning device 3, foot pad conveying device 5 and pressing mechanism 6 can be provided with two groups, and the spinning head 4 is correspondingly provided with two groups, and the assembly station 11 is correspondingly provided with two groups, and the two groups can be respectively used to convey and assemble foot pads 92 to two assembly stations 11. The two groups of components can be used to convey and assemble foot pads 92 of the same model at the same time, and the double-station assembly of the foot pads 92 can further improve the production efficiency; the two groups of components can also be used to convey and assemble foot pads 92 of different models, one group of components is running, and the other group of components is stopped. In this way, when assembling foot pads 92 of different models, only the corresponding group of components needs to be switched to run, and no downtime is required, which is very convenient and further improves the production efficiency.

The sensing sheet 73 is fixed on the test rod 71 by screwing or welding and the like. The sensor 74 is arranged on the rack 1 by screwing or welding and the like, and is used to sense the position of the sensing sheet 73. In this way, after the workpiece 91 is assembled with the foot pad 92, the workpiece conveying device 2 conveys the workpiece 91 to the detection station 12, and then the test rod driving member 72 drives all the test rods 71 to move towards the workpiece conveying device 2 together, so that the test rod 71 is in contact with the foot pad 92 in the corresponding foot pad mounting position. At this time, the sensor 74 senses the position of the sensing sheet 73, so as to determine whether the foot pad 92 is assembled in each foot pad mounting position of the workpiece 91, so as to further ensure the assembly quality of the foot pad 92.
