Description

Technical Field

[0001] The invention relates to the technical field of nut and screw assembly, and in particular to a disc-type feeding nut assembly machine. Background Art

[0002] In the field of fasteners, screw is a commonly used component concept. The so-called screw covers the threaded parts on fasteners such as screws and bolts. For example, a bolt consists of a head and a screw (a cylinder with external threads). In actual applications, it must be combined with a nut to play a fastening role. A stud is a fastener with threads on both ends. The threaded part is also called a screw. Unlike a bolt, a stud has no head. Because the stud connection is detachable, it is widely used in workpieces that need to be disassembled frequently. A through-thread screw is also called a full-thread screw or a full-thread screw because it is covered with threads all over its body. In actual use, it is often combined with a nut. It can be seen that the assembly of a screw and a nut is extremely common in the entire fastener industry and is an indispensable basic connection method.

[0003] Nuts, also known as nuts, have the main function of being screwed together with screws to achieve the fastening of various components. Currently, manual installation is still the mainstream method in the assembly of nuts and screws. During the specific operation, the nuts need to be screwed one by one to the predetermined position on the screw, and the nuts need to be continuously rotated during the process. When faced with a large number of nut and screw assembly tasks, the disadvantages of this manual operation method become apparent. On the one hand, the operation process is extremely time-consuming, which seriously affects work efficiency; on the other hand, it greatly increases the labor intensity of workers. Moreover, from the perspective of overall work efficiency, the efficiency of manual assembly is very low, which is difficult to meet the needs of large-scale production and has many inconveniences in practical applications.

[0004] In view of this, design research on nut assembly machines has been carried out in the prior art. Taking a nut machine disclosed with patent number ZL201920095154.1 as an example, a handheld screw is used to rotate the nuts. Although the equipment solves the problem of manually screwing nuts and improves work efficiency to a certain extent, it still exposes some obvious shortcomings in actual use. For example, the equipment uses a nut tray for feeding. This feeding method makes the nuts enter the nut conveying channel one by one. Moreover, since most nuts are hexagonal structures and a large number of nuts are placed together, it is easy to get stuck when entering the narrow feed port, which in turn affects the smoothness of the entire assembly process. Therefore, the structural design of the equipment still needs to be further optimized and improved to better meet actual production needs. Summary of the invention

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: Example

[0031] like Figures 1 to 9 As shown, The present invention collectively refers to bolts, studs, threaded screws, etc. that need to be assembled with nuts as screws. Therefore, the screw described in the present invention is a cylinder with an external thread and a nut assembled together. The present invention solves the problems of nut rotation and nut feeding. The present invention preferably uses a hand-held screw to cooperate with the nut. During the assembly process with the nut, a thrust is manually applied to the screw to keep the nut in contact with the drive wheel for assembly.

[0032] A disc-feed nut assembly machine, comprising: A base 1 is provided with a first power device 2, and a driving wheel 21 is provided on the output shaft of the first power device 2. The first power device 2 is a motor, which is connected to a power source through a wire and is provided with a switch. The motor is fixed to the base 1 through a motor bracket or the base 1 can be a motor bracket, which is convenient for fixing the slideway described later. A connecting hole is provided on the motor bracket, and a corresponding connecting hole is provided on the slideway 3, which is assembled through fasteners. The first power device 2 can also be an existing electric tool such as an electric hand drill, and the driving wheel can be connected according to the needs so that the driving wheel can rotate. The motor and the driving wheel are connected and fixed, and can be connected through a locking shaft rod, which is fixed to the output shaft of the motor, and the driving wheel 21 is sleeved on the locking shaft rod, and an anti-slip device is provided at the end of the locking shaft rod to prevent the driving wheel from falling off; The slideway 3 is obliquely mounted on the base 1. A nut positioning portion 31 is provided at the delivery end of the slideway 3. An assembly port 32 is provided at the nut positioning portion 31 of the slideway 3. In the subsequent assembly process, the screw rod can be directly aligned with the screw hole of the nut by holding the screw rod. In order to prevent the nut from falling out from the assembly port 32 while sliding down along the slideway, there is a certain height between the bottom edge of the assembly port 32 and the bottom plate 5 of the slideway. The height should be less than or equal to the minimum radial thickness from the screw hole to the outer periphery of the nut, which can prevent the nut from falling out and expose the screw hole. The depth of the slide groove of the slideway is greater than or equal to the diagonal length of the nut. The nut cannot be exposed from the slideway. The screw rod is inserted into the screw hole of the nut from the assembly port to make the nut contact with the driving wheel. The driving wheel drives the nut to rotate to complete the assembly. The present invention preferably adopts the friction drive method between the nut and the outer periphery of the driving wheel. The outer peripheral surface of the driving wheel and the outer peripheral surface of the nut or the end face edge of the nut are frictionally driven to drive the nut to rotate and be threadedly connected with the screw rod; secondly, the end face friction transmission method is selected, the nut of the nut positioning part is coaxially arranged with the assembly port and the end face of the nut is tightly fitted with the other end face of the driving friction wheel and is rotated and locked on the bolt inserted into the nut (this method is not shown in the figure); a driving part adapted to the nut is made in the center of the driving wheel, and the nut of the nut positioning part is coaxially arranged with the assembly port, pushing the nut into the moving part of the driving wheel 21 and rotating and locking it on the bolt inserted into the nut (this method is not shown in the figure).

[0033] The nut supply part 4 is arranged at the rear end of the slide 3, and the nut supply part 4 supplies nuts into the slide 3. The nut supply part 4 includes a material tray 41, a rotating disk 5 and a second power device 42. The second power device 42 is a reduction motor, which is connected to the power supply through a wire and is provided with a switch. The switch can be a foot switch, which is convenient for controlling the rotation of the reduction motor. At the same time, a speed regulating device is provided, which can control the speed of the reduction motor so that its feeding speed meets the assembly requirements, or the second power device 42 is connected to the circuit board through a wire, and the circuit board can control the forward and reverse rotation of the second power device 42 and control the second power device 42 to automatically reverse and then rotate forward in the event of a jam, so that the jammed nut changes position and the machine runs smoothly. 42 can be fixed on the bottom plate of the material tray, and can also be fixed by setting an additional reduction motor bracket. The material tray 41 includes a surrounding edge and a material tray bottom plate. The surrounding edge is set with the edge of the material tray bottom plate. The output shaft of the second power device 42 passes through the through hole of the material tray 41 and is connected and fixed with the center hole of the rotating disk 5. The second power device 42 drives the rotating disk 5 to rotate. A plurality of nut arrangement grooves 51 are evenly distributed on the rotating disk 5. The upper edge of the nut arrangement groove 51 is smoothly transitioned, and a small chamfer or a smooth transition surface can be designed. The nut arrangement grooves 51 are radially distributed around the center of the rotating disk 5. The nut arrangement grooves 51 are long strip grooves. The nut arrangement grooves 51 can be set as one or more. The present invention provides 4 embodiments, and the angle between two adjacent nut arrangement grooves 51 is 9 0°, the slot width of the nut arrangement slot 51 is greater than the thickness of one nut and less than the thickness of two nuts, the optimal width is greater than the thickness of the nut plus 3 mm, when the nut thickness is small, the width of the nut conveying chute 36 is two-thirds of the nut thickness, the nuts are placed on the rotating disk 5, the nut arrangement slot 51 allows multiple nuts to enter, the nuts entering the nut arrangement slot 51 are arranged in a straight line, and the nuts enter the nut arrangement slot 51 and are distributed vertically, a blanking hole 43 is provided at the bottom of the material tray 41, and the blanking holes 43 of the material tray 41 are smoothly transitioned on both sides, so that the excess nuts can be taken away from the blanking holes 43 without getting stuck, or a method of having a certain distance between the blanking holes 43 and the upper opening of the slide 3 is adopted, and the nuts that have not entered the slide leak out from the gap, thereby avoiding the nuts from leaking out when the slide is full. After the channel, the blanking hole 43 is blocked, and the blanking hole 43 corresponds to the upper opening of the slideway 3. The nut arrangement groove 51 rotates to the blanking hole 43, and the nuts in the nut arrangement groove 51 fall into the slideway 3 through the blanking hole 43. The material tray 41 serves as the initial storage container for nuts, and a large number of nuts to be assembled are placed inside. After the second power device 42 (reduction motor) is started, it drives the rotating disk 5 fixedly connected thereto to rotate. The nut arrangement grooves 51 designed on the rotating disk 5 are distributed in a specific radial shape, and the groove width is accurately controlled to be greater than the thickness of one nut and less than the thickness of two nuts, and the upper edge has a smooth transition, which is conducive to the smooth entry of the nuts. When the rotating disk 5 rotates, the nuts are subjected to the action of gravity and rotational force, and enter the nut arrangement grooves 51 in an orderly manner, and are arranged vertically in a straight line. As the rotating disk 5 continues to rotate,The nut arrangement slot 51 with nuts gradually turns to the blanking hole 43 at the bottom of the material tray 41. Since the blanking hole 43 corresponds precisely to the upper opening of the slideway 3, and the two sides of the blanking hole 43 are smooth and excessive to prevent material jamming, the nuts in the nut arrangement slot 51 smoothly pass through the blanking hole 43 and fall into the slideway 3. The operator can conveniently control the start and stop of the reduction motor through the foot switch, and can also use the speed regulating device to adjust the motor speed in real time according to the assembly progress, thereby regulating the nut feeding speed.

[0034] The present invention preferably cooperates with a hand-held screw rod and a nut, and the end of the screw rod is pressed into the screw hole of the nut at the assembly opening. The end of the screw rod is generally chamfered and smooth, and the end can slightly enter the screw hole of the nut. When it is stirred, the rear end surface of the nut slides along the rear side plate of the slideway to prevent the nut from being separated from the end of the screw rod, so that the nut is in contact with the outer peripheral surface of the driving wheel. The nut is stirred to make the nut contact with the outer peripheral surface of the driving wheel. The outer peripheral surface of the driving wheel and the outer peripheral surface of the nut or the end face edge of the nut are frictionally transmitted, and the nut is driven to rotate and be threadedly connected with the screw rod. The nut is separated from the slideway from the upper opening of the slideway or the assembly opening. During the rotation of the nut, due to the friction between the driving wheel and the nut, the nut is naturally driven to rotate a certain angle, so that the nut is separated from the slideway from the upper opening of the slideway, and the slideway The rear side plate will not hinder the screw from moving backward. If, during the assembly process, the nut is not separated from the slideway from the upper opening in time, the rear side plate will hinder the screw from moving backward. The nut can continue to rotate under the action of the driving wheel and move along the axial direction of the driving wheel, so that the nut can be screwed on the screw. Therefore, the assembly operation is extremely convenient and simple. The nut assembly machine is small in size, extremely low in cost, and easy to carry. The friction of the outer ring of the driving wheel is utilized. Since the outer diameter of the driving wheel is much larger than the outer diameter of the nut, the nut is driven to rotate as a speed-up transmission. The nut rotates faster, which makes the assembly speed faster. Since there is no obstacle behind the slideway, it will not block the movement of the screw. Therefore, the nut can be screwed on any position of the screw, and the driving wheel can be quickly separated from the nut. At the same time, the screw is not restricted by the nut assembly machine, thereby improving the assembly speed and efficiency.

[0035] A nut guide sleeve 52 is provided at the bottom of the rotating disk 5 at the nut arrangement groove 51. The height of the nut guide sleeve 52 is greater than the diagonal size of the nut, so that the nut can completely enter the nut guide sleeve 52. A connecting flange 53 is provided at the upper end of the nut guide sleeve 52. The combination of the nut guide sleeve 52 and the connecting flange 53 enhances the stability of the bottom structure of the rotating disk 5 to a certain extent. The nut guide sleeve 52, as a guiding component for nut arrangement, can withstand a certain nut impact force and friction force, and the connecting flange 53 can better fix the rotating disk 5 in the overall structure of the equipment by connecting with other components, which can reduce the design thickness of the rotating disk 5 and reduce the overall weight. The connecting flange 53 of the nut guide sleeve 52 is connected to the rotating disk 5 by a fastener. The connecting head 47 of the fastener protrudes from the upper surface of the rotating disk 5 to stir the nuts, change the nut arrangement on the rotating disk 5, and make the nuts easier to enter the nut guide sleeve 52. The nut supply part 4 can be used for feeding different nuts by replacing the guide sleeve.

[0036] A plurality of rollers 54 are provided at the bottom of the rotating disk 5, and the rollers 54 are evenly distributed at the bottom of the rotating disk 5, and the rollers 54 are in rolling contact with the bottom of the material tray 41. When the rotating disk 5 is in operation, the rollers 54 at the bottom are in rolling contact with the bottom of the material tray 41. This rolling contact mode enables the rotating disk 5 to rotate flexibly relative to the material tray 41. The rollers 54 are like small wheels, which convert the sliding friction between the rotating disk 5 and the material tray 41 into rolling friction. At the same time, the rollers 54 help to achieve the precise movement of the rotating disk 5 relative to the material tray 41 and improve the carrying capacity of the rotating disk 5. The rollers 54 include balls, a jacket and a connecting screw. The rolling arrangement of the balls is fixed in the jacket by a pressure ring, and the connecting screw is arranged at the upper end of the jacket and connected to the corresponding connecting hole on the rotating disk 5, and can be locked and fixed by a nut.

[0037] A baffle 44 is provided in the material tray 41 above the rotating disk 5. The baffle 44 divides the material tray 41 into two areas, including a nut placement area and a nut conveying area. The drop hole 43 is located in the nut conveying area, and the nut is placed in the nut placement area. In this way, when the nut falls into the slide from the nut guide sleeve 52, it will not be disturbed by the nuts on the rotating disk 5 that have not entered the nut guide sleeve 52, thereby ensuring smooth feeding. As the rotating disk 5 rotates, the baffle 44 can sweep the nuts on the rotating disk 5 into the nut arrangement groove 51, thereby increasing the probability of the nuts entering the nut arrangement groove 51.

[0038] A baffle brush 45 is provided on the baffle bar 44. The baffle brush 45 can be made of a flexible thin pad or bristles, which can block the nuts to a certain extent, and at the same time prevent the nuts that have not fully entered the nut arrangement groove 51 from being stuck by the baffle bar 44, causing the machine to run unsmoothly, thereby ensuring that the rotating disk 5 is not restricted by the baffle bar 44 and ensures smooth operation.

[0039] Two flange couplings 46 are fixed on the output shaft of the second power device 42. The two flange couplings 46 are symmetrically arranged on the upper and lower surfaces of the rotating disk 5. Corresponding connecting holes are provided on the rotating disk 5 and the flange coupling 46. The rotating disk 5 is fixed between the two flange couplings 46 by fasteners to ensure the firmness of the connection. The flange coupling 46 is provided with radial threaded holes, and the top screw is screwed in the radial threaded holes to support the output shaft of the second power device 42.

[0040] The slide 3 includes a front side plate 33, a bottom plate 34 and a rear side plate 35. The front side plate 33 and the rear side plate 35 are connected on both sides of the bottom plate 34. A nut conveying chute 36 is formed between the front side plate 33 and the rear side plate 35. The above describes a method for solving the problem of handling the nuts at the blanking holes 43 after the nuts in the slide are filled. Here, a solution is further proposed. When using a non-adjustable slide, the height of the nut conveying chute 36 can be made to be similar to the diagonal size of the nuts. When the nuts in the slide are filled, the nuts at the blanking holes 43 can be taken back to the material tray 41 by the nut guide sleeve 52. During use, it is only necessary to replace the slide that is compatible with the nuts. The nut positioning portion 31 is located at the front end of the bottom plate 34, and the nut can slide along the bottom plate 34. The nut that abuts against the nut positioning portion 31 has a screw hole that is opposite to the assembly port 32. Figure 2 The nut positioning portion 31 is located at the front end of the bottom plate 34 and is a protrusion, which can prevent the nut from moving forward. Figure 3 The nut positioning portion 31 includes a shaft 81 and a sleeve 82. The shaft 81 is connected to the front side plate 33 and the rear side plate 35. The sleeve 82 is sleeved on the shaft 81 and can rotate. The advantage of this connection is that the nut slides along the rear side plate 35, and the nut will contact the sleeve, making the nut move more smoothly. At the same time, when the nut contacts the driving wheel, the nut will collide with the sleeve 82 without causing scratches.

[0041] A guide plate 37 is provided at the rear end of the slide 3. The guide plate 37 and the side plate of the slide 3 are bent. The guide plate 37 can support the material tray 41. The guide plate 37 and the material tray 41 are detachably connected by fasteners to facilitate the replacement of different slides. The guide plate 37 is provided with a strip hole adapted to the fastener. At the same time, the guide plate 37 guides the nut at the drop hole 43 at the bottom of the material tray 41, so that the nut quickly enters the slide.

[0042] A first support rod 11 and a second support rod 12 are provided on the base 1. The first support rod 11 is connected to the slide 3, and the second support rod 12 is connected to the material tray 41, which can support the slide 3 and the material tray 41. The second support rod 12 can also be arranged in multiple numbers to ensure structural stability and is fixed to the material tray 41 by welding or fasteners.

[0043] The bottom plate 34 is composed of a plurality of thin plates, the rear end of which is located at the blanking hole 43, and gaskets 8 are arranged between the thin plates to increase the width of the nut conveying chute 36, thereby expanding the width of the upper opening of the slideway 3, making it easier for the nut to enter the slideway.

[0045] The present invention provides four types of nuts after filling the slideway. The first type adjusts the rotation speed of the second power device to make the nut feeding speed and assembly speed equal to each other to ensure assembly; the second type controls the rotation of the second power device by a foot switch to rotate only when necessary to control the feeding; the third type, such as Fig. 9 As shown, discharge holes 7 are opened on the guide plates on both side plates of the slide, or a method of having a certain distance between the discharge hole and the upper opening of the slide is adopted, and the nuts that have not entered the slide leak out from the gap; the height of the fourth nut conveying chute can be made to be close to the diagonal size of the nut. When the nuts in the slide are filled, the nuts at the discharge holes can be taken back to the material tray by the nut guide sleeve. During use, only the slide that is compatible with the nuts needs to be replaced. The above four solutions can be selected according to usage requirements. This embodiment combines the second and fourth methods to improve control accuracy.

[0046] Working principle: The driving wheel and the nut of the present invention are driven by friction. The use method of the present invention includes the following preparations: A large number of nuts to be assembled are placed in the nut placement area in the tray 41. The tray serves as the initial storage container for the nuts. The second power device 42 (reduction motor) is connected to the power supply system through a wire. The appropriate connection method can be selected according to the actual situation, such as parallel connection or single connection. If a single connection is used, ensure that it is correctly connected to the foot switch, circuit board and power cord; if parallel, it must be electrically connected to other related components such as the first power device, the main switch and the power adapter as required, and at the same time confirm that the relevant functional components such as the speed control device can be used normally. When ready, turn on the main switch (if any) to put the equipment in an operational state.

[0047] Start-up and delivery: The operator starts the second power device 42 (reduction motor) through the foot switch, or controls its start-up through the circuit board (if this control method is adopted), and the reduction motor drives the rotating disk 5 fixedly connected thereto to start rotating. The nut arrangement grooves 51 designed on the rotating disk 5 are distributed in a radial shape, and the groove width is precisely controlled to be greater than the thickness of one nut and less than the thickness of two nuts. The upper edge has a smooth transition, which is conducive to the smooth entry of the nuts. When the rotating disk 5 rotates, the nuts are subjected to the combined action of gravity and rotational force, and enter the nut arrangement grooves 51 in an orderly manner and are arranged in a vertical line. As the rotating disk 5 continues to rotate, the nuts are installed. The nut arrangement groove 51 with nuts gradually turns to the drop hole 43 at the bottom of the material tray 41. Since the drop hole 43 corresponds precisely to the upper opening of the slide 3, and the two sides of the drop hole 43 are smooth to prevent jamming, the nuts in the nut arrangement groove 51 pass through the drop hole 43 smoothly and fall into the slide 3, realizing the conveying process of the nuts from the material tray to the slide. During this process, the baffle bar 44 can sweep the nuts on the rotating disk 5 into the nut arrangement groove 51, increasing the probability of the nuts entering, and the baffle brush 45 can prevent the nuts that have not fully entered the nut arrangement groove 51 from being stuck by the baffle bar 44, thereby ensuring the smooth operation of the rotating disk 5.

[0048] Nut and screw assembly Screw Insertion Preparation: The operator holds the screw rod and pushes the end of the screw rod into the screw hole of the nut at the assembly opening 32. Usually, the end of the screw rod is chamfered and smooth, so that it can slightly enter the screw hole of the nut. During operation, the rear end surface of the nut slides along the rear side plate of the slideway 3 to prevent the nut from being separated from the end of the screw rod. Drive rotation and assembly: By stirring the nut, the nut is brought into contact with the outer peripheral surface of the driving wheel 21, and the outer peripheral surface of the driving wheel is frictionally transmitted with the outer peripheral surface of the nut or the end face edge of the nut (the outer peripheral surface friction driving method is preferably adopted), driving the nut to rotate, and then threadedly connected with the screw. During the rotation of the nut, due to the friction between the driving wheel and the nut, the nut will naturally rotate a certain angle, so that the nut will be separated from the slideway from the upper opening of the slideway 3, and the assembly is completed. If the nut is not separated from the slideway from the upper opening in time during the assembly process, the rear side plate will not hinder the screw from moving backward. Under the action of the driving wheel, the nut can continue to rotate and move along the axial direction of the driving wheel, and the nut can also be threadedly connected to the screw, thereby realizing a relatively convenient and simple nut and screw assembly operation.

[0049] During the entire working process, the first power device 2 provides rotational power for the driving wheel 21, and the second power device 42 provides power for the nut supply. The various components work together to continuously complete the assembly of the nut and the screw. In addition, the speed regulating device can be used to adjust the feed speed of the second power device 42 in real time according to actual assembly requirements. At the same time, the relevant control components in the power supply system (such as foot switches, circuit boards, etc.) are used to conveniently control the start and stop of the power device to ensure that the assembly work is carried out efficiently and smoothly. Example

[0050] like Figures 10 to 12 As shown, the structure of a disc-feed nut assembly machine in this embodiment is basically the same as that of a disc-feed nut assembly machine in Example 1, except that the slideway structure is different. In this embodiment, the slideway 3 is an adjustable slideway, and the front side plate 33 of the slideway 3 is connected to the bottom plate 34 to form a whole. An adjustment plate 38 adapted to the bottom plate 34 is formed at the bottom of the rear side plate 35, and a longitudinal adjustment hole 39 is provided on the adjustment plate 38. A positioning hole is provided on the bottom plate 34, and a fixing rod 6 is provided at the positioning hole. The fixing rod 6 passes through the longitudinal adjustment hole 39 and is connected to the fixing cap 61. By adjusting the connection position of the fixing rod 6 and the longitudinal adjustment hole 39, the distance between the front side plate 33 and the rear side plate 35 can be adjusted. The front side plate 33 of the slide 3 is connected to the bottom plate 34 to form a whole, and the adjustment plate 38 at the bottom of the rear side plate 35 is adapted to the bottom plate 34. A longitudinal adjustment hole 39 is provided on the adjustment plate 38, and a positioning hole is provided at a corresponding position of the bottom plate 34. The fixing rod 6 passes through the longitudinal adjustment hole 39 and is connected to the fixing cap 61. In this way, the spacing between the front side plate 33 and the rear side plate 35 can be adjusted by changing the connection position of the fixing rod 6 and the longitudinal adjustment hole 39. This adjustable design can flexibly adjust the width of the slide according to the size requirements of nuts of different specifications, ensure the smooth transportation of the nuts in the slide, and avoid the nuts from getting stuck or falling off due to the slide being too wide or too narrow.

[0051] The nut positioning portion 31 includes a connecting rod 62 and a block body 63. A transverse adjustment hole 64 is provided on the base plate 34 at the assembly port 32. The connecting rod 62 passes through the transverse adjustment hole 64 and is connected and fixed to the block body 63. The nut positioning portion 31 is composed of a connecting rod 62 and a block body 63. A transverse adjustment hole 64 is provided on the base plate 34 at the assembly port 32. The connecting rod 62 passes through the transverse adjustment hole 64 and is connected and fixed to the block body 63. Therefore, the transverse position of the block body 63 can be adjusted as needed, so that the nut positioning portion 31 can accurately position nuts of different specifications, ensuring that when the nut reaches the assembly port 32, its screw hole can be accurately aligned with the assembly port, facilitating subsequent assembly operations with the screw rod.

[0052] A discharge port 7 is provided on a side plate at the rear end of the slide 3 located at the drop hole 43. A discharge port 7 is provided on a side plate at the rear end of the slide 3 located at the drop hole 43. Its function is that when some abnormal situations occur, such as unqualified nuts or excess nuts entering the slide, these unnecessary things can be discharged from the slide through the discharge port 7 to avoid affecting the normal nut conveying and assembly process, thereby ensuring the stability and reliability of the entire assembly machine.

[0053] The distance between the front side plate 33 and the rear side plate 35 at the rear end of the slide 3 is greater than the distance between the front side plate 33 and the rear side plate 35 at the front end of the slide 3. The distance between the front side plate 33 and the rear side plate 35 at the rear end of the slide 3 is greater than the distance between the front side plate 33 and the rear side plate 35 at the front end of the slide 3. Such a design helps to better receive the nuts dropped from the blanking hole 43, and provides a relatively looser space for the nuts to enter the slide, so that the nuts can smoothly enter the slide and be transported forward. At the same time, it can also reduce the problems such as jamming of the nuts due to sudden changes in space at the moment of entering the slide to a certain extent.

[0054] The nut conveying chute 36 is provided with a guide bar 71, which is in contact with the rear side plate 35, and the rear side plate 35 is provided with a vertical adjustment hole 72. The guide bar 71 is provided with an adjustment rod 73, which passes through the vertical adjustment hole 72 and is connected to the adjustment cap 74. The nut conveying chute 36 is provided with a guide bar 71, which is in contact with the rear side plate 35, and the rear side plate 35 is provided with a vertical adjustment hole 72. The guide bar 71 is provided with an adjustment rod 73, which passes through the vertical adjustment hole 72 and is connected to the adjustment cap 74. By adjusting the connection position of the adjustment rod 73 and the vertical adjustment hole 72, the vertical height of the guide bar 71 can be changed, and then the guiding effect of the guide bar 71 on the nut can be adjusted according to the actual size, thickness, etc. of the nut, to ensure that the nut is stably conveyed along a suitable path in the slide, thereby further improving the accuracy and smoothness of the entire assembly process.

[0055] In summary, the adjustable designs of the slideway 3 and its related components enable the disc-feed nut assembly machine to better adapt to nuts of different specifications and diversified assembly requirements, thereby improving the versatility and work efficiency of the equipment.

[0056] The best embodiment of the present invention has been described, and various changes or modifications made by those skilled in the art will not depart from the scope of the present invention.
