Description

Technical Field

[0001] This invention belongs to the field of hardware tool manufacturing technology, and in particular relates to a fully automatic oil pressure cup device. Background Technology

[0002] In the hardware tool manufacturing industry, some pliers (such as wire cutters and needle-nose pliers) typically have an oil filling hole near the hinge. For example, Chinese utility model patent CN217596862U discloses a pair of pliers with a long-lasting lubrication effect, which includes a first pliers body and a second pliers body. Both the first and second pliers bodies have pin holes inside, and the first and second pliers bodies are connected by pins provided inside the pin holes. The first pliers body has an oil reservoir located on the contact surface between the first and second pliers bodies; the second pliers body has an oil filling hole that communicates with the oil reservoir.

[0003] When slow-release grease is injected into the grease filling hole of this type of pliers, the grease can enter the pin joint hole and lubricate the contact surfaces of the first and second pliers. In the prior art, in order to seal the grease filling hole, a seal is often inserted into the grease filling hole. When it is necessary to add grease to the grease filling hole again, the seal must be removed. Since the seal is difficult to remove, in the prior art, a pressure cup (i.e., the existing grease nipple) is often pressed into the grease filling hole. Slow-release grease can be added into the grease filling hole simply by pressing down the steel ball of the pressure cup.

[0004] See Figure 16 As shown, the product 10 involved in this application is the pliers described above, in which an oil cup 103 is pressed into the oil injection hole 102 of the pliers body 101.

[0005] Since the pressure cup serves as the seal and injection channel for the oil filling hole, its pressing quality directly affects the product's performance and lifespan. Currently, the pressing operation of the aforementioned pressure cup 103 is mostly completed manually or semi-automatically. The operator first manually places the clamps on a simple positioning fixture, injects slow-release grease into the oil filling hole using an injection gun, then manually takes the bulk pressure cup, aligns it with the oil filling hole, and hammers or presses it in using a hammer or pneumatic press. This traditional processing method has the following shortcomings: 1. Low efficiency: Each process requires manual operation, resulting in a slow cycle time and difficulty in meeting the needs of mass production; 2. Poor positioning accuracy: The manual placement of the clamp body and the positioning of the oil injection hole rely on visual inspection. When pressing the oil cup, defects such as skewing, incomplete pressing, or damage to the oil cup are prone to occur. 3. Uneven oil injection: Manual oil injection is difficult to control precisely, and problems such as injecting too much or too little oil are prone to occur; 4. High labor intensity: Long-term repetitive manual operation can easily lead to operator fatigue and pose safety hazards such as finger crushing.

[0006] Although there are some automatic pressing equipment in the existing technology, most of them are for pressing general parts (such as bearings, pins, etc.). They lack integrated and fully automatic technical solutions for the unique shape and structure of the clamp body, the position of the oil injection hole and the feeding characteristics of the oil cup. This is a technical problem that urgently needs to be solved in the industry.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0008] To address the technical problems existing in the prior art, this application provides a fully automatic oil cup device that integrates feeding, positioning, oil injection, feeding, pressing, and unloading to achieve fully automatic cyclic operation.

[0009] To achieve the above objectives, the present invention provides the following technical solution: A fully automatic oil pressure cup device, comprising: frame; A cam dividing mechanism, mounted on the frame, is used to drive the clamp body to index between the positioning station, the oiling station, the pressing station, and the unloading station. A positioning mechanism is provided at the positioning station for positioning the clamp body; The oiling mechanism is located at the oiling station and is used to automatically and quantitatively inject oil into the clamp body after positioning. A pressing mechanism, located at the pressing station, is used to press the oil cup into the oil injection hole of the clamp body; A feeding mechanism is located outside the pressing station and is used to automatically supply the pressing oil cup to the pressing mechanism; The unloading mechanism is located at the unloading station and is used to automatically unload the product that has completed oil injection and pressing of the oil cup. The feeding mechanism is located on one side of the positioning station and is used to feed individual clamps one by one into the positioning mechanism; The electrical control system is electrically connected to the above-mentioned mechanisms and is used to control the automatic cyclic execution of each action.

[0010] Preferably, the positioning and holding mechanism includes a positioning plate on the turntable of the cam dividing mechanism at the positioning station, oiling station, pressing station, and unloading station; a pressure plate spanning above the positioning plate; and an elastic component below the pressure plate. The positioning plate has a positioning groove for accommodating the clamp body and for initially positioning the clamp body. The elastic component pulls down the pressure plate to press against the clamp body in the positioning groove. A lifting mechanism is also provided on the frame below the turntable at the positioning station and unloading station. The lifting mechanism can compress the elastic component to lift the pressure plate.

[0011] Preferably, the elastic component includes two sliding columns vertically fixedly connected to both sides of the positioning plate and respectively slidably disposed within the turntable, a spring sleeved on the sliding column below the turntable, a lifting plate sleeved on the two sliding columns below the spring, and a locking nut fixedly connected to the two sliding columns below the lifting plate; the lifting mechanism can lift the lifting plate and compress the spring to lift the pressure plate.

[0012] Preferably, the feeding mechanism includes a feeding linear module vertically mounted on the frame, a sliding frame fixedly connected to the sliding component of the feeding linear module, a hopper vertically mounted on the sliding frame, a feeding cylinder mounted on the frame, and a push plate fixedly connected to the telescopic rod of the feeding cylinder; multiple partitions are evenly distributed along the height direction inside the hopper, and a single clamp is placed on each partition; the feeding linear module drives the hopper to rise, and the feeding cylinder drives the push plate to push the single clamps one by one into the positioning slot at the positioning station.

[0013] Preferably, the unloading mechanism includes an unloading bracket on a frame located outside the unloading station, a horizontally mounted unloading push cylinder on the unloading bracket, a vertically mounted unloading clamping cylinder on the telescopic rod of the unloading push cylinder, and a gripper for picking up and placing products at the output end of the unloading clamping cylinder; the unloading push cylinder and the unloading clamping cylinder cooperate to clamp the product located in the positioning slot at the unloading station into the unloading box.

[0014] Preferably, the positioning mechanism includes a positioning bracket fixedly connected to the fixed plate of the cam dividing mechanism, a positioning cylinder vertically downwardly arranged on the positioning bracket, and a positioning column fixedly connected to the telescopic rod of the positioning cylinder. A tapered positioning cone is provided at the lower end of the positioning column. The positioning cylinder drives the positioning cone to descend into the oil injection hole of the clamp body located in the positioning groove at the positioning station, so as to realize the positioning of the clamp body.

[0015] Preferably, the feeding mechanism includes a circular vibrating mechanism mounted on the outer frame of the pressing station, a linear vibrating mechanism connected to the outlet of the circular vibrating mechanism, a material distribution block connected to the outlet of the linear vibrating mechanism, and a material distribution mechanism for distributing the oil cups in the material distribution block one by one; the oil cups in the circular vibrating mechanism are conveyed to the material distribution block by the linear vibrating mechanism and then distributed by the material distribution mechanism, and the pressing mechanism presses the distributed oil cups into the oil injection hole of the clamp body located below the material distribution block.

[0016] Preferably, the material distribution block and the material distribution mechanism are fixedly connected to the fixed plate of the cam dividing mechanism; a guide groove is provided at the front end of the material distribution block along its length, a material distribution groove is vertically provided on the upper surface of the material distribution block at the guide groove, the guide groove at the rear end of the material distribution groove can only accommodate one pressure cup and a material discharge hole penetrating the material distribution block is vertically provided at the bottom of the groove, and a material blocking groove penetrating the side of the material distribution block is horizontally provided in the middle of the material distribution block at the rear end of the material distribution groove; the material distribution mechanism includes a material distribution bracket, and on the material distribution bracket... The system includes a material dispensing cylinder, a material dispensing plate and a material baffle plate fixedly connected to the telescopic rod of the material dispensing cylinder, and staggered material passage grooves and clearance grooves on the material dispensing plate and the material baffle plate, respectively. The material dispensing plate and the material baffle plate are slidably embedded in the material dispensing groove and the material baffle groove, respectively. When the telescopic rod of the material dispensing cylinder reciprocates, the oil cup is fed when the material passage groove is aligned with the discharge port of the linear vibration mechanism, and the material is dispensed when the material passage groove is aligned with the discharge hole, and the material is blocked when the material passage groove is aligned with the discharge hole.

[0017] Preferably, the pressing mechanism includes a pressing bracket mounted on the frame, a pressing cylinder mounted vertically downward on the pressing bracket, and a pressing rod fixedly connected to the telescopic rod of the pressing cylinder; the pressing cylinder drives the pressing rod to press the oil cup in the guide groove at the rear end of the material distribution groove into the oil injection hole of the clamp body through the material discharge hole.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. The cam-driven indexing mechanism integrates the functions of feeding, positioning, oiling, pressing, and unloading into a single workstation, allowing each workstation to operate synchronously and in parallel. Each rotation of the cam divider completes the unloading, positioning, oiling, and pressing of one product simultaneously, enabling continuous cyclical operation and significantly improving efficiency compared to manual and semi-automatic methods.

[0019] 2. A two-stage positioning system is employed: initial positioning with a positioning groove and secondary precision positioning with a positioning cone. The positioning groove conforms to the shape of the clamp body, ensuring that the initial error between the oil injection hole and the set position is controlled within 3mm. Then, a positioning cylinder drives a positioning cone with a tapered surface to insert into the oil injection hole, using the guiding action of the cone to forcefully push the clamp body to the precise position. This structure effectively overcomes the cumulative errors caused by feeding and turntable operation, ensuring that the oil injection hole of each clamp body is located in the preset standard position. This provides a precise reference for subsequent oil injection and pressing, avoiding oil injection deviation or poor oil cup pressing due to positional deviation.

[0020] 3. The feeding mechanism uses a combination of circular and linear vibration to achieve automatic alignment and conveying of oil cups. The distribution block integrates guide grooves, positioning cavities, discharge holes, and a distribution plate and baffle plate driven by a single distribution cylinder. Through a single reciprocating motion of the distribution cylinder, the distribution, baffle, and discharge of oil cups are completed simultaneously, eliminating the need for additional distribution drive components, simplifying the structure, reducing costs, and ensuring stable and reliable distribution.

[0021] 4. The feeding mechanism combines layered material storage in a hopper with linear module step-lifting, and works with a pusher plate to automatically push each clamp body into its position. The unloading mechanism uses a combination of unloading push cylinders and unloading clamping cylinders to automatically grab and transfer the material to the unloading box. The entire process requires no manual intervention, thus eliminating the safety risks associated with manual operation. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Example

[0041] See appendix Figure 1 , 2 As shown in Figure 3, a fully automatic oil cup device is used to realize the fully automatic feeding, precise positioning, automatic oil injection, automatic oil nozzle delivery and pressing, and automatic unloading process during the processing of product 10, thereby automating the entire process of oil injection and oil cup pressing of the clamp body 101. It should be noted that the product 10 in this embodiment is the clamp described in the background art, which has an oil injection hole 102 on the clamp body 101 and an oil cup 103 pressed into the oil injection hole 102.

[0042] The fully automatic oil cup pressing device includes a frame 1, a cam dividing mechanism 2, a positioning mechanism 3, an oil injection mechanism 4, a pressing mechanism 5, a feeding mechanism 6, a discharging mechanism 7, a loading mechanism 8, and a positioning and holding mechanism 9.

[0043] Specifically, the frame 1 includes a frame-type support frame 11 and a support plate 12 that is horizontally fixed to the upper end of the support frame 11 by bolts.

[0044] See Figure 1 , 4 As shown, the cam dividing mechanism 2 is fixedly mounted on the support plate 12. The cam dividing mechanism 2 is an existing four-position cam divider 23 driven by a motor 21 and a synchronous pulley assembly 22. The motor 21 is fixedly mounted on the lower end face of the support plate 12 by bolts, and the cam divider 23 is fixedly mounted on the upper end face of the support plate 12 by bolts. The synchronous pulley assembly 22 passes through the clearance groove of the support plate 12.

[0045] A turntable 24 is horizontally fixed to the rotating output end of the cam divider 23 by bolts. A fixed plate 25 is horizontally fixed to the fixed output end of the cam divider 23 by bolts. The fixed plate 25 is located above the turntable 24 and is fixed in place. The outer diameter of the fixed plate 25 is smaller than the outer diameter of the turntable 24. The motor 21 drives the synchronous belt pulley assembly 22 and the cam divider 23, which in turn drives the turntable 24 to rotate in an indexing manner, realizing a four-position synchronous cyclic operation. This is existing technology and will not be described in detail.

[0046] See Figure 2 , 3 As shown, for ease of description, the four stations of the cam divider 23 are divided according to their functions as follows: a positioning station 13 for positioning the clamp body 101, an oiling station 14 for oiling the oiling holes 102 on the clamp body 101, a pressing station 15 for pressing the oil cup 103 into the oiling holes 102, and a unloading station 16 for unloading the finished product (product 10) after the oil cup 103 has been pressed. The cam dividing mechanism 2 drives the clamp body 101 to index between the positioning station 13, the oiling station 14, the pressing station 15, and the unloading station 16.

[0047] See Figure 5 As shown, it is a positioning and holding mechanism 9, which is used to fix the clamp body 101 after positioning to prevent the clamp body 101 from shaking during rotation and causing positioning failure.

[0048] The positioning and holding mechanism 9 includes a positioning plate 91 set on the turntable 24 of the cam dividing mechanism 2 at the positioning station 13, the oiling station 14, the pressing station 15 and the unloading station 16, a pressure plate 92 spanning above the positioning plate 91, and an elastic component set below the pressure plate 92. The positioning plate 91 has a positioning groove 911 that accommodates the clamp body 101 and can perform preliminary positioning of the clamp body 101. The elastic component pulls down the pressure plate 92 to press the clamp body 101 into the positioning groove 911.

[0049] See Figure 16 As shown, the positioning groove 911 has an outward-facing opening structure to allow the clamp body 101 to be pushed into the positioning groove 911 through the opening. The positioning groove 911 is a contoured structure that matches the shape of the clamp body 101, completing the initial positioning of the clamp body 101 after it is pushed into the positioning groove 911. It should be noted that, in order to further refine the positioning of the clamp body 101 located in the positioning groove 911 by the positioning mechanism 3, so that the oil injection hole 102 is in the set position, the error between the oil injection hole 102 and the set position after the clamp body 101 enters the positioning groove 911 shall not exceed 3mm. The positioning plates 91 on both sides of the positioning groove 91 are provided with waist-shaped adjustment holes of the conventional structure along their length direction to facilitate the adjustment of the fixed position of the positioning plates 91 on the turntable 24.

[0050] See Figure 6 As shown, the elastic component includes two sliding columns 93 that are vertically fixed to both sides of the positioning plate 91 by bolts and respectively slidable in the turntable 24, a spring 94 sleeved on the sliding column 93 below the turntable 24, a lifting plate 95 sleeved on the two sliding columns 93 below the spring 94, and a locking nut 96 fixedly connected to the two sliding columns 93 below the lifting plate 95.

[0051] To further secure the lifting plate 95, a limiting nut 961 is threaded between the lifting plate 95 and the lower end of the spring 94. The locking nut 96 and the limiting nut 961 together fix the lifting plate 95 to the two sliding columns 93. In addition, to improve the smoothness of the sliding column 93 when it slides up and down and to guide it, a sliding sleeve 931 is fixedly embedded in the turntable 24 on both sides of the positioning plate 91, and the sliding column 93 slides through the sliding sleeve 931.

[0052] Thus, under the elastic force of the spring 94, the lifting plate 95 is pushed to move downward, which in turn drives the sliding column 93 and the pressure plate 92 to move downward, so that the pressure plate 92 presses against the upper end face of the clamp body 101 located in the positioning groove 911, thereby completing the fixation of the clamp body 101.

[0053] See Figure 4 , 8 As shown, in order to disengage the pressure plate 92 from the clamp body 101, a lifting mechanism is also provided on the support plate 12 below the turntable 24 at the positioning station 13 and the unloading station 16. The lifting mechanism can compress the spring 94 of the elastic component to lift the pressure plate 92.

[0054] Specifically, the lifting mechanism includes a lifting bracket 97 bolted to the lower end face of the support plate 12 and a lifting cylinder 98 bolted vertically to the lifting bracket 97. The telescopic rod of the lifting cylinder 98 is slidably inserted into the support plate 12 and extends above it. When the telescopic rod of the lifting cylinder 98 retracts, it disengages from the lifting plate 95, and when it extends, it pushes the lifting plate 95 and the pressure plate 92 upward.

[0055] See Figure 8 As shown, the positioning mechanism 3 is set at the positioning station 13 and is used to position the clamp body 101.

[0056] The positioning mechanism 3 includes a positioning bracket 31 fixedly connected to the fixed plate 25 of the cam dividing mechanism 2 by bolts, a positioning cylinder 32 fixedly connected vertically downward on the positioning bracket 31, and a positioning column 33 fixedly sleeved on the telescopic rod of the positioning cylinder 32. A tapered positioning cone 34 is provided at the lower end of the positioning column 33. The outer diameter of the positioning cone 34 matches the inner diameter of the oil injection hole 102 according to the set positioning error. That is, when the telescopic rod of the positioning cylinder 32 extends, it can drive the positioning column 33 and the positioning cone 34 to descend until the positioning cone 34 enters the oil injection hole 102. When the axis of the oil filling hole 102 does not coincide with that of the positioning cone 34, since the lower end of the positioning cone 34 is a conical structure, its tip first enters the oil filling hole 102. As the positioning cone 34 continues to descend, the entire positioning cone 34 enters the oil filling hole 102. During this process, the clamp body 101 will move to the set position under the push of the positioning cone 34, thereby completing the precise positioning of the clamp body 101 and the oil filling hole 102 on it.

[0057] See Figure 1 , 7 As shown, in order to automatically feed each clamp 101 into the positioning groove 911 of the positioning plate 91 located at the positioning station 13, the present invention also provides a feeding mechanism 8. The feeding mechanism 8 is located on one side of the positioning station 13 and is used to feed each clamp 101 into the positioning groove 911 one by one.

[0058] Specifically, the feeding mechanism 8 includes a feeding linear module 81 vertically fixedly connected to the support plate 12, a sliding frame 82 fixedly connected to the sliding part of the feeding linear module 81 by bolts, a hopper 83 vertically fixedly connected to the sliding frame 82 by bolts, a feeding bracket 84 fixedly connected to the support plate 12, a feeding cylinder 85 horizontally fixedly connected to the feeding bracket 84, and a push plate 86 fixedly connected to the telescopic rod of the feeding cylinder 85.

[0059] In this embodiment, the feeding linear module 81 is a screw transmission mechanism driven by an existing servo motor and is designed as a sunken structure, that is, its lower part is located below the support plate 12. The feeding linear module 81 can drive the hopper 83 to rise through the clearance slot opened on the support plate 12.

[0060] The hopper 83 has a rectangular cross-section and multiple horizontally fixed partitions 87 are evenly distributed along its height. Each partition holds a single clamp 101. The feeding linear module 81 drives the hopper 83, partitions 87, and clamps 101 to rise synchronously, making the uppermost clamp 101 horizontally aligned with the positioning slot 911. The feeding cylinder 85 drives the push plate 86 to push the single clamp 101 into the positioning slot 911 at the positioning station 13. The feeding linear module 81 drives the hopper 83 to rise to the same height each time, ensuring that the uppermost clamp 101 is always aligned with the corresponding positioning slot 911, thereby pushing all the clamps 101 in the entire hopper 83 into the positioning slot 911 one by one.

[0061] To make the structure of the feeding mechanism 8 more compact and to facilitate the pusher plate 86 in pushing out the clamp 101, in this embodiment, the pusher plate 86 includes a vertical plate 861 that is vertically fixed to the telescopic rod of the feeding cylinder 85 by bolts, and a horizontal plate 862 that is horizontally fixed to the upper end face of the vertical plate 861 by bolts. The horizontal plate 862 is located above the feeding cylinder 85. A horizontal plate through groove 863 is provided at the front end of the horizontal plate 862 along its length. When the telescopic rod of the feeding cylinder 85 extends to drive the horizontal plate 862 forward, the horizontal plate through groove 863 avoids the vertical end face of the hopper 83. The horizontal plate 862 on the side of the horizontal plate through groove 863 near the feeding linear module 81 passes through the hopper 83 and pushes the clamp 101 on the partition plate 87 into the corresponding positioning groove 911.

[0062] See Figure 3 As shown, the oiling mechanism 4 is located at the oiling station 14 and is used to automatically and quantitatively inject oil into the clamp body 101 after it has been positioned by the positioning mechanism 3.

[0063] Specifically, the oil filling mechanism 4 includes an oil filling bracket 41 fixedly installed on a fixed plate 25 at the oil filling station 14 by bolts, an oil filling cylinder 42 fixedly installed vertically downward on the oil filling bracket 41 by bolts, a clamping block 43 fixedly installed on the telescopic rod of the oil filling cylinder 42 by bolts, and an oil filling bottle 44 fixedly clamped vertically downward in the clamping block 43.

[0064] Specifically, the clamping block 43 has various structural forms, such as a clamping structure or a clamping hole. The oil bottle 44 is fixedly clamped in the clamping hole. The oil bottle 44 is existing technology and can realize timed and quantitative automatic oil filling into the oil filling hole 102 on the clamp body 101.

[0065] After the clamp body 101 is precisely positioned by the positioning mechanism 3 at the positioning station 13, the telescopic rod of the lifting cylinder 98 retracts, and the pressure plate 92 presses the clamp body 101. While achieving the positioning of the clamp body 101, it also ensures that the clamp body 101 will shake when it rotates with the turntable 24 to the oiling station 14, so as not to cause positioning failure.

[0066] After the clamp body 101, which has been precisely positioned, rotates to the oil filling station 14, the telescopic rod of the oil filling cylinder 42 extends to drive the oil filling bottle 44 down to the oil outlet of the oil filling bottle 44 approaching the oil filling hole 102. Then, the oil filling bottle 44 automatically injects a set amount of lubricating oil into the oil filling hole 102 and stops. The telescopic rod of the oil filling cylinder 42 retracts to drive the oil filling bottle 44 back to its original position. After oil filling, the clamp body 101 rotates with the turntable to the pressing station 15.

[0067] See Figure 3 As shown, a pressing mechanism 5 and a feeding mechanism 6 are provided at the pressing station 15. The feeding mechanism 6 is located on the outside of the pressing station 15 and is used to automatically supply the oil cup 103 to the pressing mechanism 5. The pressing mechanism 5 is used to press the oil cup 103 into the oil injection hole 102 of the clamp body 101.

[0068] See Figure 9 , 10 As shown, the feeding mechanism 6 includes a circular vibration mechanism 61 mounted on a support plate 12 of the frame 1 outside the pressing station 15, a linear vibration mechanism 62 connected to the outlet of the circular vibration mechanism 61, a material distribution block 63 fixedly connected to the fixed plate 25 and connected to the outlet of the linear vibration mechanism 62, and a material distribution mechanism 64 that distributes the oil cups 103 in the material distribution block 63 one by one. The oil cups 103 in the circular vibration mechanism 61 are conveyed to the material distribution block 63 by the linear vibration mechanism 62 and then distributed by the material distribution mechanism 64. The pressing mechanism 5 then presses the distributed oil cups 103 into the oil injection hole 102 of the clamp body located below the material distribution block 63. The circular vibration mechanism 61 and the linear vibration mechanism 62 are both existing technologies. By arranging the oil cups 103, they can push the oil cups 103 into the material distribution block 63 one by one in sequence, thereby realizing continuous and automatic feeding of the oil cups 103.

[0069] See Figure 12 , 13As shown, a connecting plate 631 is formed by bending upwards at the rear end of the material distribution block 63. An oblong adjustment through-hole is provided on the connecting plate 631, and bolts are inserted into this adjustment through-hole to fix the connecting plate 631 to the fixing plate 25. A guide groove 632 is provided at the front end of the material distribution block 63 along its length, and the guide groove 632 is aligned and connected with the discharge port of the linear vibration mechanism 62. A material distribution groove 633 is vertically formed on the upper surface of the material distribution block 63 at the guide groove 632, and the material distribution groove 633 is perpendicular to the guide groove 632. The guide groove 632 at the rear end of the material distribution groove 633 forms a positioning cavity 634. This positioning cavity 634 can only accommodate one pressure cup 103, and the groove wall at the rear end of the positioning cavity 634 is set as an arc portion that matches the outer circumference of the pressure cup 103, in order to position the pressure cup 103 at this location. A vertical discharge hole 635 is provided at the bottom of the positioning cavity 634, penetrating the material distribution block 63. A horizontal retaining groove 636 is provided at the middle of the material distribution block 63 at the rear end of the material distribution groove 63, penetrating the side of the material distribution block 63. The bottom of the retaining groove 636 is located above the bottom of the material distribution groove 633, and the retaining groove 636 is connected to the material distribution groove 633. The inner diameter of the arc portion of the positioning cavity 634, the inner diameter of the discharge hole 635, and the inner diameter of the oil injection hole 102 are matched, that is, after a single oil cup 103 fits against the arc portion of the positioning cavity 634, it can enter the oil injection hole 102 through the discharge hole 635.

[0070] See Figure 11 As shown, the material distribution mechanism 64 includes a material distribution bracket 641 fixedly connected to the fixed plate 25 by bolts, a material distribution cylinder 642 horizontally fixedly connected to the material distribution bracket 641 by bolts, a material distribution plate 643 and a baffle plate 644 fixedly connected to the telescopic rod of the material distribution cylinder 642 by bolts. The material distribution plate 643 and the baffle plate 644 are respectively provided with staggered material passage grooves 645 and clearance grooves 646. The dimensions of the material passage grooves 645 and the clearance grooves 646 are both larger than the dimensions of the pressure cup 103, that is, the pressure cup 103 can pass through the material passage grooves 645 and the clearance grooves 646.

[0071] The material distribution plate 643 and the baffle plate 644 are slidably embedded in the material distribution groove 633 and the baffle groove 636, respectively. In this embodiment, the material passage groove 645 is arranged in front of the avoidance passage groove 646.

[0072] When the telescopic rod of the distributing cylinder 642 reciprocates, the oil cup 103 is fed when the material passage 645 is aligned with the discharge port of the linear vibration mechanism 62, and the material is distributed when the material passage 645 is aligned with the discharge port of the linear vibration mechanism 62.

[0073] Specifically, when the telescopic rod of the dispensing cylinder 642 is retracted, the material passage 645 is located at the guide groove 632, avoiding the misalignment of the passage 646 with the discharge hole 635 and being located behind the discharge hole 635. At this time, the circular vibration mechanism 61 and the linear vibration mechanism 62 guide the pressure cup 103 through the guide groove 632 and the material passage 645 into the positioning cavity 634. Due to the blocking effect of the baffle plate 644, the pressure cup 103 cannot fall into the discharge hole 635.

[0074] When the telescopic rod of the distributing cylinder 642 is extended, it drives the distributing plate 643 and the baffle plate 644 to move forward until the material passage groove 645 and the guide groove 632 are misaligned, and the clearance groove 646 is aligned with the discharge hole 635. When the distributing plate 643 moves forward, it achieves the distributing and blocking of the aligned oil cups 103. That is, through the squeezing action of the distributing plate 643, the oil cups 103 on both sides of the distributing plate 643 are separated, and the oil cups 103 in the guide groove 632 are prevented from entering the positioning cavity 634 again, so that only one oil cup 103 is retained in the positioning cavity 634. At this time, the oil cup 103 in the positioning cavity 634 enters the discharge hole 635 through the clearance groove 646.

[0075] By setting up a material distribution plate 643 and a baffle plate 644, and opening a material distribution groove 633 and a baffle groove 636 respectively, the material distribution, baffle and unloading process of the pressure oil cup 103 can be realized by setting up only one material distribution cylinder 642.

[0076] See Figure 1 , 10 As shown, the pressing mechanism 5 includes a pressing bracket 51 fixedly connected to the support plate 12 by bolts, a pressing cylinder 52 fixedly connected vertically downward on the pressing bracket 51, and a pressing rod 53 fixedly connected to the telescopic rod of the pressing cylinder 52. The pressing rod 53 is coaxially arranged with the material discharge hole 635 and the oil injection hole 102 on the clamp body 101 located at the pressing station 15 after positioning.

[0077] See Figure 14 The diagram illustrates the process by which the pressing rod 53 presses the oil cup 103 from the discharge hole 635 into the oil injection hole 102. As described above, when the telescopic rod of the distributing cylinder 642 extends, the telescopic rod of the pressing cylinder 52 extends to drive the pressing rod 53 downward, passing through the positioning cavity 634 and the clearance groove 646 into the discharge hole 635, and continues to descend to push the oil cup 103 into the oil injection hole 102, thereby completing the pressing of the oil cup 103. It should be noted that the lower part of the oil cup 103 has an inwardly tapered structure, which facilitates its pressing into the oil injection hole 102. Afterward, the telescopic rod of the pressing cylinder 52 retracts, driving the pressing rod 53 to move to the initial position above the distributing block 63.

[0078] See Figure 1 , 15As shown, the unloading mechanism 7 is set at the unloading station 16 and is used to automatically unload the clamp body 101 after the oil filling and pressing of the oil cup are completed.

[0079] Specifically, the unloading mechanism includes an unloading bracket 71 bolted to a support plate 12 on the outside of the unloading station 16, an unloading push cylinder 72 bolted horizontally to the unloading bracket 71, a mounting plate 73 bolted vertically downward to the telescopic rod of the unloading push cylinder 72, an unloading clamping cylinder 74 bolted vertically downward to the outer side of the mounting plate 73, and a gripper 75 for picking up and placing the finished product 10 at the output end of the unloading clamping cylinder 74; the unloading clamping cylinder 74 can be an existing finger cylinder.

[0080] In addition, a feeding plate 76 is fixedly connected to the support plate 12 below the feeding push cylinder 72 at an angle downward. The two sides of the feeding plate 76 are bent upward to form a feeding channel. The lower end outlet of the feeding plate 76 is inserted into the feeding box 77 located on one side of the frame 1.

[0081] The unloading push cylinder 72 and the unloading clamping cylinder 74 work together to clamp the product 10 in the positioning groove 911 located at the unloading station 16 into the unloading box 77.

[0082] In order to realize the automatic operation of this fully automatic oil cup device, the device also includes an electrical control system (not shown in the figure). The electrical control system is existing technology and is electrically connected to the above-mentioned cam dividing mechanism 2, positioning mechanism 3, oil injection mechanism 4, pressing mechanism 5, feeding mechanism 6, unloading mechanism 7, loading mechanism 8, and positioning and holding mechanism 9, and is used to control the automatic cyclic execution of each action.

[0083] The working principle and process of this embodiment are as follows: The fully automatic oil cup device is used to realize the automatic oil injection and oil cup assembly of product 10. The entire working process is based on the four-station cam divider 23 driving the turntable 24 to rotate intermittently, so that the clamp body 101 passes through the positioning station 13, the oil injection station 14, the pressing station 15 and the unloading station 16 in sequence. Each station performs the corresponding action synchronously to realize fully automatic cyclic operation.

[0084] 1. Automatic feeding of clamp body After the device is started, the feeding mechanism 8 begins to work. First, the lifting cylinder 98 located below the positioning station 13 is extended, and its telescopic rod lifts the lifting plate 95 upwards. This compresses the spring 94 via the sliding column 93 and lifts the pressure plate 92, reserving space for the clamp 101 to enter the positioning slot 911. The feeding linear module 81 drives the hopper 83 to rise, aligning the uppermost partition 87 and the individual clamps 101 on it horizontally with the positioning slot 911 on the positioning plate 91 at the positioning station 13. Subsequently, the feeding cylinder 85 extends, driving the horizontal plate 862 of the push plate 86 through the hopper 83, pushing the clamp 101 horizontally into the positioning slot 911 at the positioning station 13, completing the initial positioning of the individual clamp 101. The feeding cylinder 85 retracts, and the feeding linear module 81 rises again to a set height, positioning the next clamp 101, ready for the next push.

[0085] 2. Precision positioning of the clamp body When the clamp body 101 is pushed into the positioning groove 911, the telescopic rod of the positioning cylinder 32 extends, causing the positioning column 33 and the lower positioning cone 34 to descend. Because the lower end of the positioning cone 34 has a conical structure, even if there is a positional deviation of no more than 3mm in the oil filling hole 102 of the clamp body 101, the tip of the positioning cone 34 can enter the oil filling hole 102 first, and as it continues to descend, the conical surface guides the clamp body 101 to a precisely set position, completing the precise positioning of the oil filling hole 102 and the clamp body 101. Afterwards, the telescopic rod of the lifting cylinder 98 retracts, and its telescopic rod disengages from the lifting plate 95. Under the restoring force of the spring 94, the lifting plate 95, the sliding column 93, and the pressure plate 92 move downwards synchronously, and the pressure plate 92 presses against the upper end face of the clamp body 101, thus fixing the clamp body 101. The telescopic rod of the positioning cylinder 32 retracts, and the positioning cone 34 rises to its reset position. At this time, the pressure plate 92 keeps the clamp body 101 pressed, ensuring that the position of the clamp body 101 remains fixed when the turntable 24 rotates.

[0086] 3. Automatic oiling of the clamp body The cam divider 23 drives the turntable 24 to rotate 90°, delivering the positioned clamp 101 to the oiling station 14. The pressure plate 92 continues to press the clamp 101 to prevent shaking. The oiling mechanism 4 is activated: the extension rod of the oiling cylinder 42 extends, causing the oil bottle 44 to descend, bringing its oil outlet close to the oiling hole 102 on the clamp 101. The oil bottle 44 automatically injects lubricating oil into the oiling hole 102 according to the preset amount. After completion, the extension rod of the oiling cylinder 42 retracts, and the oil bottle 44 returns to its original position. The oiled clamp 101 is then ready to move to the next station along with the turntable 24.

[0087] 4. Automatic feeding of the oil pressure cup At the pressing station 15, the feeding mechanism 6 continuously supplies the pressing oil cups 103. The circular vibration mechanism 61 and the linear vibration mechanism 62 arrange the pressing oil cups 103 and convey them one by one into the guide groove 632 of the material distribution block 63. The material distribution mechanism 64 works together to achieve single material distribution: initially, the material distribution cylinder 642 is in the retracted state, the material passage groove 645 on the material distribution plate 643 is aligned with the guide groove 632, and a pressure cup 103 enters the positioning cavity 634 (while being blocked by the baffle plate 644 and unable to fall); then the telescopic rod of the material distribution cylinder 642 extends, the material distribution plate 643 and the baffle plate 644 move forward synchronously, the material passage groove 645 is misaligned with the guide groove 632, thereby blocking the subsequent pressure cup 103 outside, realizing material distribution and blocking; at the same time, the clearance groove 646 on the baffle plate 644 moves to align with the discharge hole 635, and the pressure cup 103 in the positioning cavity 634 falls into the discharge hole 635 by gravity, waiting for pressing.

[0088] 5. Automatic pressing After the feeding mechanism 6 delivers an oil cup 103 to the discharge hole 635, the pressing mechanism 5 activates. The telescopic rod of the pressing cylinder 52 extends, causing the pressing rod 53 to descend. The pressing rod 53 first enters the positioning cavity 634 of the material distribution block 63, passes through the clearance groove 646, and then enters the discharge hole 635, pushing the oil cup 103 therein to continue descending, precisely pressing the oil cup 103 into the oil filling hole 102 of the clamp body 101 located directly below it, which has already been filled with oil. After pressing into place, the telescopic rod of the pressing cylinder 52 retracts, and the pressing rod 53 rises to reset. At this time, the oil cup 103 has been firmly pressed into the oil filling hole 102, completing the finished product assembly.

[0089] 6. Automatic feeding The cam divider 23 rotates 90° again, sending the pressed product 10 to the unloading station 16. The lifting cylinder 98 below this station extends, lifting the lifting plate 95 and causing the pressure plate 92 to rise, releasing the pressure on the product 10. The unloading mechanism 7 operates as follows: the telescopic rod of the unloading push cylinder 72 extends to move the unloading clamping cylinder 74 above the product 10, and the unloading clamping cylinder 74 drives the gripper 75 to close, clamping the product 10; the telescopic rod of the unloading push cylinder 72 retracts, pulling the product 10 horizontally out of the positioning slot 911; then the unloading clamping cylinder 74 drives the gripper 75 to release, and the product 10 falls onto the inclined unloading plate 76, sliding along the unloading channel into the unloading box 77.

[0090] The above six steps are executed in a cycle. Every time the cam divider 23 rotates once (four stations), it completes the synchronous processing of four clamps 101 (one per station). That is, one clamp completes the unloading, one completes the positioning, one completes the oiling, and one completes the pressing, thereby realizing fully automatic and highly efficient continuous production.

[0091] It should be noted that, The electrical control system of this fully automatic oil cup press can use a programmable logic controller (PLC) or an industrial microcontroller as the control core. Its connection method and control principle with the above-mentioned cam dividing mechanism 2, positioning mechanism 3, oil injection mechanism 4, pressing mechanism 5, feeding mechanism 6, unloading mechanism 7, loading mechanism 8, and positioning and holding mechanism 9 are all conventional technologies in the field of industrial automation. As long as the above working process can be met, it is acceptable. Those skilled in the art can directly select and connect according to the mechanical action flow without creative labor, and will not be elaborated here.

[0092] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
