Technical Field
[0001] This invention relates to the field of clamp installation equipment technology, and more specifically to installation equipment for clamps on liner cores. Background Technology
[0002] As a commonly used component in various mechanical parts, the outer wall of the liner usually needs to be fitted with clamps to achieve functions such as positioning, anti-loosening, sealing or connection and fixation, so as to ensure the reliability of the overall assembly structure. At present, most of the liner clamps in the industry are installed manually, by manually opening the clamps and then fitting them into the designated position of the liner to complete the clamp installation.
[0003] However, the existing technology has the following problems:
[0004] The manual installation of clamps is not only inefficient and labor-intensive, but also prone to problems such as clamp misalignment and clamp deformation. Furthermore, repeated operation can easily cause hand injuries to operators, making it difficult to meet the needs of batch, high-efficiency, and stable production. Summary of the Invention

[0017] The beneficial effects are:
[0018] 1. This equipment for installing clamps on lining cores, through the coordinated operation of the material guiding mechanism, the execution mechanism, the limiting mechanism and the installation shaft, enables the worker to automatically install the lining core onto the clamp each time it is installed. This is achieved by inserting the lining core into the insertion hole of the installation shaft and pushing it into place. Simultaneously, the next lining core is installed in place. Compared with manually installing lining core clamps, this greatly improves work efficiency and avoids injury to the worker's fingers.
[0019] 2. This installation device for clamps on the liner core, through the setting of the lubrication component, allows the sliding column to drive the installation shaft to reciprocate multiple times. After the installation disc rotates once, the atomizing nozzle sprays lubricant onto the surface of the installation shaft once. When the clamp slides along the surface of the installation shaft, the lubricant can be evenly applied. By spraying lubricant onto the surface of the installation shaft, the sliding between the clamp and the installation shaft, as well as the sliding between the installation shaft and the half sleeve, can be made smoother, thereby reducing wear. In addition, the operator can adjust the lubrication frequency by increasing or decreasing the number of protrusions on the installation disc according to the actual lubrication needs.
[0020] 3. The installation equipment for the clamp on the liner core, through the setting of the support mechanism, allows the rollers to automatically move upward and temporarily support the installation shaft when the two half sleeves are far apart, so as to share the support pressure of the sensing shaft and reduce the wear of the sensing shaft.

[0046] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.
[0047] Please see Figure 1 - Figure 8 In one embodiment:
[0048] The device for installing clamps on the liner core includes a worktable 1, which is equipped with a material guiding mechanism 2, an execution mechanism 3, and a limiting mechanism 4. It also includes an installation shaft 5, one end of which has an insertion hole for inserting the liner core, and the other end has a boss. The outer surface of the installation shaft 5 near the boss is designed as a frustum-shaped structure. The installation shaft 5 is the core component for docking the clamp with the liner core. Its insertion hole is used to accurately position the liner core, keeping the liner core and the installation shaft 5 coaxial. The boss is used to cooperate with the execution mechanism 3 to realize the reciprocating movement of the installation shaft 5. The frustum-shaped structure is used to open the clamp. When the installation shaft 5 moves, the clamp will be gradually opened along the frustum surface, expanding its inner diameter to match the size of the liner core installation position, laying the foundation for the subsequent clamp to be fitted onto the liner core. At the same time, the frustum structure can make the clamp opening process smooth and avoid damage to the clamp due to uneven force.
[0049] Furthermore, the material guiding mechanism 2 is used to guide the clamp onto the motion trajectory of the outer wall of the mounting shaft 5. The material guiding mechanism 2 includes a guide plate 21, which is mounted on the workbench 1. A material trough is provided on the guide plate 21, with an inlet and an outlet. The inlet of the material trough is connected to the upstream feeding equipment, and a hinged door 22 is connected to the outlet of the material trough. A first cylinder 24 is mounted on the workbench 1, and a push block 23 is connected to the output end of the first cylinder 24. When the push block 23 moves, it can push the clamp in the material trough to the outlet. Two support blocks 25 are mounted on the guide plate 21. The support block 25 is mirror-image positioned below the material trough outlet. The support block 25 is horizontally slidably connected to the guide plate 21. A first connecting rod 26 is hinged to the support block 25, and a first slider 27 is vertically slidably connected to the guide plate 21. The end of the first connecting rod 26 away from the support block 25 is hinged to the first slider 27. A spring is provided between the first slider 27 and the guide plate 21. The core function of the guiding mechanism 2 is to achieve orderly conveying and precise positioning of the clamps, ensuring that the clamps can accurately enter the movement trajectory of the mounting shaft 5, preparing for subsequent installation. The material trough on the guide plate 21 is L-shaped. The outlet is located at the bottom, allowing the clamps conveyed by the upstream feeding equipment to be stacked vertically, preventing the clamps from getting messy and stuck. The material trough inlet is connected to the upstream feeding equipment to realize automatic feeding of the clamps. The flip door 22 is normally closed to prevent clamps that have not been pushed from falling prematurely. When the push block 23 pushes the bottom clamp towards the outlet, the clamp will push open the flip door 22 and enter the outlet. After the clamp falls, the flip door 22 automatically swings down and closes, ensuring that subsequent clamps fall in an orderly manner onto the movement trajectory of the push block 23, realizing the one-to-one delivery of clamps. The support block 25 is equipped with a matching mechanism to the outer wall of the clamp. The notch allows the clamp to be stably placed on the support block 25, providing precise positioning for the installation shaft 5 to pass through the clamp. The support block 25, together with the first connecting rod 26, the first slider 27 and the spring, forms an elastic adjustment structure. When the clamp is opened, the clamp will drive the two support blocks 25 away from each other. When the support block 25 moves, the first connecting rod 26 pulls the first slider 27 up and compresses the spring, so that the notch of the support block 25 is always in contact with the outer wall of the clamp, maintaining the stability of the clamp. When the clamp is detached from the support block 25, the two support blocks 25 return to their original position and are in contact, preparing for the next clamp to be received.
[0050] Specifically, the limiting mechanism 4 includes two half-sleeves 42. When the mounting shaft 5 moves, the two half-sleeves 42 can dislodge the clamps on the mounting shaft 5 and place them onto the insert core within the mounting shaft 5's insertion hole. The limiting mechanism 4 includes a base 41, which is mounted on the worktable 1. Both half-sleeves 42 are horizontally slidably mounted on the base 41. Each half-sleeve 42 has a semi-circular groove on its side closest to each other that matches the outer wall of the mounting shaft 5. When the semi-circular grooves on the sides of the two half-sleeves 42 are joined together, they form a circular channel that matches the outer wall of the mounting shaft 5. When the two half-sleeves 42 are closed... The circular channel can limit and guide the mounting shaft 5, ensuring that the mounting shaft 5 will not deviate when it moves. At the same time, the left edge of the semi-circular groove can block the clamp on the mounting shaft 5. When the mounting shaft 5 continues to move, the clamp will be blocked by the edge of the semi-circular groove and stop moving with the mounting shaft 5. Then it will slide off the outer wall of the mounting shaft 5 onto the liner inserted into the insertion hole, thus realizing the installation of the clamp. When the two half-sleeves 42 move away from each other, the circular channel opens, allowing the mounting shaft 5 to drive the clamp through smoothly and deliver the clamp to the left edge of the half-sleeve 42, preparing for the next installation.
[0051] In addition, the actuator 3 is used to drive the mounting shaft 5 to move. The actuator 3 includes a slide column 31, which is horizontally slidably mounted on the worktable 1. The worktable 1 is provided with a second cylinder 32 for driving the slide column 31 to translate. A slide seat 33 is vertically slidably connected to the top of the slide column 31. A third cylinder 35 is provided on the top of the slide column 31 for driving the slide seat 33 to move vertically. A fork plate 34 is mounted on the slide seat 33. A fourth cylinder 36 is horizontally mounted through the slide column 31. The output end of the fourth cylinder 36 is connected to a sensing shaft 37. The fork plate 34 is provided with a fork that can engage with the boss of the mounting shaft 5. When the fork plate 34 moves, it can drive the mounting shaft 5 to move through the boss. A round hole is provided on the boss of the mounting shaft 5, and the sensing shaft 37 can be inserted into the round hole of the boss. The sensing shaft 37 is provided with a sensing head for driving the actuator 3 to start. The second cylinder 32 serves as... The power source for the horizontal movement of the sliding column 31, through its telescopic motion, can precisely drive the sliding column 31 to move left and right. The third cylinder 35 drives the sliding block 33 to move vertically, realizing the docking and disengagement of the fork plate 34 with the boss of the mounting shaft 5. When the third cylinder 35 drives the sliding block 33 to move downward, the fork of the fork plate 34 is engaged with the left edge of the boss of the mounting shaft 5, facilitating the subsequent movement of the mounting shaft 5 to the right. When the third cylinder 35 drives the sliding block 33 to move upward, the fork plate 34 disengages from the boss of the mounting shaft 5, avoiding affecting the reset of the mounting shaft 5. The fourth cylinder 36 drives the sensing shaft 37 to move horizontally. The sensing shaft 37 can be inserted into the round hole of the boss of the mounting shaft 5, which on the one hand provides support and positioning for the mounting shaft 5, and on the other hand, when the sensing head on the sensing shaft 37 is contacted by the round hole of the boss, it will trigger the actuator 3 to start, starting the automatic operation process, realizing the automated triggering of clamp installation, and improving installation accuracy and efficiency.
[0052] In addition, a second slider 44 is vertically slidably connected to the base 41. Two second connecting rods 43 are hinged to the second slider 44. The ends of the two second connecting rods 43 away from the second slider 44 are respectively hinged to two half sleeves 42. A groove block 46 is connected to the sliding column 31. A guide groove is provided on the groove block 46. A crossbar 45 is connected to the second slider 44. A sliding shaft 451 is connected to the crossbar 45. The sliding shaft 451 is slidably connected to the guide groove. When the groove block 46 approaches the second slider 44, it can drive the second slider 44 to move upward through the sliding cooperation of the guide groove and the sliding shaft 451. The upward movement of the second slider 44 can cause the two half-sleeves 42 to move away from each other via the two second connecting rods 43; when the second slider 44 moves upward, it can cause the two half-sleeves 42 to open via the two second connecting rods 43, and when the second slider 44 moves downward, it can cause the two half-sleeves 42 to close via the two second connecting rods 43. The groove block 46 moves synchronously with the sliding column 31. The guide groove on the groove block 46 is trapezoidal, divided into a bottom edge, a left inclined edge, a top edge, and a right inclined edge, and a chamfer is provided between the left inclined edge and the bottom edge. From the time the sliding shaft 451 enters the left inclined edge until it leaves the left inclined edge, the sliding shaft 451 is guided by the guide groove. Similarly, after the sliding shaft 451 enters the right inclined side and moves down to reset, when the mounting shaft 5 moves to the right, the two semi-sleeves 42 close, so that the clamp fitted on the outer wall of the mounting shaft 5 near its insertion hole can be stopped from moving to the right by the left edge of the semi-circular groove of the two semi-sleeves 42. As the mounting shaft 5 continues to move to the right, the clamp gradually slides along the outer wall of the mounting shaft 5 to the left end. When the left end of the mounting shaft 5 retracts into the semi-sleeve 42, the liner inserted in the insertion hole of the mounting shaft 5 moves to the inside of the clamp. After the clamp falls off the outer wall of the mounting shaft 5, it is directly fitted onto the liner. The liner and the insertion hole... The insertion position is exactly the installation position of the clamp, so that after the clamp is detached from the mounting shaft 5, it can be directly inserted into the clamp installation position of the liner core, thus achieving the technical effect of fitting the clamp onto the liner core. When the mounting shaft 5 moves to the left, the two half-sleeves 42 separate from each other, so that the clamp fitted on its surface moves to the left synchronously when the mounting shaft 5 moves to the left. When the mounting shaft 5 returns to its original position, the clamp passes between the two open half-sleeves 42 and moves to the left edge of the half-sleeves 42, thus achieving the technical effect of conveying the clamp to the left edge of the half-sleeves 42, so that the next rightward movement of the mounting shaft 5 can realize the installation of the clamp.
[0053] Please see Figure 1 , Figure 9 - Figure 11 In another embodiment:
[0054] The workbench 1 is equipped with a lubrication assembly 6, which includes a mounting bracket 61. The mounting bracket 61 is mounted on the workbench 1, and a liquid cylinder 62 and an air cylinder 65 are mounted on the mounting bracket 61. A liquid pipe 63 is connected to the bottom of the liquid cylinder 62, and an atomizing nozzle 64 is connected to the end of the liquid pipe 63 away from the liquid cylinder 62. The atomizing nozzle 64 is located above the mounting shaft 5. An air pipe is connected between the air cylinder 65 and the liquid cylinder 62. A turntable 66 is mounted on the workbench 1, and a gear ring 67 and a mounting plate 68 are rotatably mounted on the turntable 66. A ratchet and pawl mechanism is provided between the mounting shaft 68 and the mounting plate 7. A rack 610 is connected to the bottom of the sliding column 31, and the rack 610 meshes with the gear ring 67. The mounting plate 68 has multiple mounting holes, and protrusions 69 are detachably mounted on the mounting holes. During the movement, the protrusions 69 can contact and squeeze the air cylinder 65. The liquid cylinder 62 is used to store lubricant. The liquid pipe 63 connects the liquid cylinder 62 to the atomizing nozzle 64 to realize the delivery of lubricant. The atomizing nozzle 64 is arc-shaped, surrounds the outside of the mounting shaft 5, and has a circumferential shape. The array has multiple nozzles that atomize the lubricant and spray it evenly onto the surface of the mounting shaft 5, ensuring lubrication of the entire circumference of the mounting shaft 5. When the air cylinder 65 is compressed, it injects air into the liquid cylinder 62. Using positive pressure, the lubricant in the liquid cylinder 62 is pushed through the liquid pipe 63 to the atomizing nozzle 64, realizing automatic lubricant spraying. The rack 610 moves to the right, causing the gear ring 67 to rotate clockwise, and moves to the left, causing the gear ring 67 to rotate counterclockwise. The ratchet and pawl mechanism between the gear ring 67 and the mounting plate 68 forms a unidirectional mechanism. In the transmission structure, when the gear ring 67 rotates counterclockwise, it drives the mounting plate 68 to rotate synchronously; when it rotates clockwise, it does not drive the mounting plate 68 to rotate. Therefore, each time the slide column 31 completes one reciprocating motion, it will drive the mounting plate 68 to rotate in one direction by a certain angle. The protrusions 69 on the mounting plate 68 can be detached and installed. When the mounting plate 68 rotates, the protrusions 69 will contact and squeeze the air cylinder 65, triggering the spraying of lubricant. The operator can adjust the lubrication frequency by increasing or decreasing the number of protrusions 69 on the mounting plate 68 according to the actual lubrication needs.
[0055] Please see Figure 4 , Figure 12 In another embodiment:
[0056] A support mechanism 7 is mounted on the base 41. The support mechanism 7 includes a telescopic rod 71, which is mounted on the base 41. A roller 72 is mounted on the top of the telescopic section of the telescopic rod 71. A square groove is formed between the two semi-sleeves 42, and the roller 72 and the telescopic rod 71 are located in the square groove. Two third connecting rods 73 are hinged to the outer wall of the telescopic section of the telescopic rod 71. The ends of the two third connecting rods 73 away from the telescopic rod 71 are respectively hinged to the inner walls of the square grooves of the two semi-sleeves 42. When the two semi-sleeves 42 move away from each other, the telescopic rod 71 can be extended upward by the two third connecting rods 73. The telescopic rod 71 is divided into a fixed section and a telescopic section, which can realize vertical extension and retraction. The roller 72 has elastic deformation capability. The square groove between the two semi-sleeves 42 provides installation space for the telescopic rod 71 and the roller 72, avoiding the need for support. When the opening and closing action of the support mechanism 7 and the half sleeve 42 interferes, when the two half sleeves 42 open away from each other, the telescopic section of the telescopic rod 71 will be pulled upward through the third link 73, causing the roller 72 to move upward and contact the bottom outer wall of the mounting shaft 5, providing temporary support for the mounting shaft 5 and sharing the support pressure of the sensing shaft 37, thus preventing the sensing shaft 37 from wearing and deforming due to long-term stress. When the clamp contacts the roller 72, the elastic deformation of the roller 72 allows the clamp to pass smoothly without affecting the movement trajectory of the clamp. When the two half sleeves 42 close together, the telescopic section of the telescopic rod 71 will be pushed to retract through the third link 73, causing the roller 72 to move downward and disengage from the mounting shaft 5, thus avoiding unnecessary friction caused by long-term contact between the roller 72 and the mounting shaft 5, and ensuring the normal movement of the mounting shaft 5.
[0057] When the installation equipment for the clamps on the lining core is in operation, the upstream feeding device feeds the clamps one by one into the material trough of the guide plate 21. The material trough is L-shaped with the outlet at the bottom. The clamps in the material trough are stacked vertically in sequence. The push block 23 is located in the middle of the material trough next to the bottommost clamp. After the first cylinder 24 is activated, the push block 23 moves into the material trough and pushes the bottommost clamp towards the hinged door 22. When the clamp moves, it pushes open the hinged door 22 and enters the material trough outlet, and then falls onto the two support blocks 25. Then, the hinged door 22 closes, and the next clamp falls onto the movement trajectory of the push block 23. Both support blocks 25 have recesses that match the outer wall of the clamp. These recesses on the two support blocks 25 can support the falling clamp, ensuring it is positioned on the movement trajectory of the mounting shaft 5. The guide plate 21 has openings for the mounting shaft 5 to pass through. In its initial state, the end of the mounting shaft 5 with the insertion hole protrudes beyond the two half-sleeves 42, while the end of the boss is located next to the clamp on the support block 25 (e.g., ...). Figure 5 As shown), insert the liner into the insertion hole of the mounting shaft 5, and then push the mounting shaft 5 to retract it into the two half sleeves 42, causing the liner to move towards the guide plate 21. When the liner moves, its boss first passes through the clamp. The following text refers to... Figure 4As shown, the diameter of the frustum-shaped structure of the mounting shaft 5 decreases from left to right. Therefore, after the boss passes through the clamp, as the mounting shaft 5 continues to move to the right, the clamp is gradually stretched along the frustum-shaped structure. At the same time, the edge of the opening of the guide plate 21 abuts against the clamp, preventing the clamp from moving to the right with the mounting shaft 5. When the round hole of the boss contacts the sensing head, the sensing shaft 37 is inserted into the round hole. After the sensing head is contacted, the actuator 3 is triggered to run. The working stroke of the actuator 3 is divided into five strokes. In the first stroke, the third cylinder 35 drives the slide 33 to move down, causing the slide 33 to drive the fork of the fork plate 34 to move down and lock onto the left edge of the boss of the mounting shaft 5. Then the second stroke is triggered, and the second cylinder 32 drives the slide column 31 to move to the right. The slide column 31 drives the slide 33 and the fork plate 34 to move to the right synchronously, so that the fork plate 34 passes through The edge of the boss pulls the entire mounting shaft 5 to the right. After the mounting shaft 5 moves to the right, the clamp finally slides to the outer wall of the end of the mounting shaft near the insertion hole, and then triggers the third stroke. The second cylinder 32 drives the slide column 31 to move to the left to reset. At the same time, the sensing shaft 37 abuts against the boss and pushes the entire mounting shaft 5 to the left. After the slide column 31 resets, the fourth stroke is triggered. The third cylinder 35 drives the slide block 33 to move upward to reset, so that the fork plate 34 disengages from the mounting shaft 5. Then the fifth stroke is triggered. The fourth cylinder 36 drives the sensing shaft 37 to move to the left and then to the right to reset. When the sensing shaft 37 moves to the left, it uses the boss to push the mounting shaft 5 to the left. When the sensing shaft 37 moves to the right, it is pulled out from the round hole of the boss and disengages from the mounting shaft 5. At this time, the mounting shaft 5 has been reset to the initial state, and the clamp on the mounting shaft 5 is just located at the edge of the left end of the two half sleeves 42.
[0058] When the sliding column 31 moves left and right, it drives the groove block 46 to move synchronously. The guide groove on the groove block 46 is trapezoidal, and the trapezoidal guide groove is divided into a bottom edge, a left hypotenuse, a top edge, and a right hypotenuse. A chamfer is provided between the left hypotenuse and the bottom edge of the trapezoid. When the groove block 46 moves to the right, the sliding shaft 451 slides along the bottom edge of the trapezoidal guide groove. When the groove block 46 moves to the right, the sliding shaft 451 enters the left hypotenuse guided by the chamfer. When the groove block 46 moves to the left, the sliding shaft 451 first slides along the left hypotenuse, then enters the top edge, and finally enters the right hypotenuse before returning to the bottom edge. The process of the sliding shaft 451 from entering the left hypotenuse until leaving the left hypotenuse is recorded. In the middle, the sliding shaft 451 is guided by the guide groove and moves upward a certain distance. Similarly, after the sliding shaft 451 enters the right inclined side, it moves downward to reset. Therefore, during the entire process of the groove block 46 moving towards the second slider 44, it first drives the crossbar 45 and the second slider 44 upward through the sliding shaft 451, then maintains the current state, and finally drives the second slider 44 downward. Furthermore, when the groove block 46 moves away from the second slider 44, the second slider 44 remains unchanged at first, and finally moves upward a small distance when the sliding shaft 451 enters the chamfer of the left inclined side. When the second slider 44 moves upward, it can be driven by the two second connecting rods 43. The two semi-sleeves 42 are spread apart. After the second slider 44 moves down, it drives the two semi-sleeves 42 to move closer together and close through the two second connecting rods 43. Therefore, when the mounting shaft 5 moves to the right, the two semi-sleeves 42 close, so that the clamp fitted on the outer wall of the mounting shaft 5 near its insertion hole can be stopped from moving to the right by the left edge of the semi-circular groove of the two semi-sleeves 42. As the mounting shaft 5 continues to move to the right, the clamp gradually slides along the outer wall of the mounting shaft 5 to the left end. When the left end of the mounting shaft 5 retracts into the semi-sleeves 42, the liner inserted in the insertion hole of the mounting shaft 5 moves to the inside of the clamp. After the clamp falls off from the outer wall of the mounting shaft 5, it directly... The clamp is fitted onto the liner, and the insertion position of the liner and the insertion hole is exactly the installation position of the clamp. This allows the clamp to be directly inserted into the clamp installation position of the liner after it is detached from the mounting shaft 5, thus achieving the technical effect of fitting the clamp onto the liner. When the mounting shaft 5 moves to the left, the two half-sleeves 42 separate from each other, causing the clamp fitted on its surface to move to the left synchronously when the mounting shaft 5 moves to the left. When the mounting shaft 5 returns to its original position, the clamp passes between the two open half-sleeves 42 and moves to the left edge of the half-sleeves 42, thus achieving the technical effect of conveying the clamp to the left edge of the half-sleeves 42, so that the next rightward movement of the mounting shaft 5 can achieve the installation of the clamp.
[0059] In simple terms, the installation of the clamp involves two steps: the first step is manual, and the second step is automatic. In the first step, the liner is inserted into the mounting shaft 5's insertion hole and pushed to the right until the sensing shaft 37 is inserted into the boss's round hole. This triggers the second step, where the actuator 3 moves the mounting shaft 5 to the right and then to the left to return to its initial state. In the first step, the boss at the right end of the mounting shaft 5 inserts into the clamp, causing the clamp to first fit onto the frustum-shaped structure. In the second step, the clamp first slides to a position close to the insertion hole, and then follows the mounting shaft 5 to move to the left of the two half-sleeves 42. When repeating the above steps again, in the first step, the clamp is blocked by the two half-sleeves 42 and disengages from the mounting shaft 5, eventually locking onto the liner. In the second step, the next clamp is moved by the mounting shaft 5 to the left side of the half-sleeve 42 to await the next installation. Therefore, each time the liner clamp is installed, the worker inserts the liner into the insertion hole of the mounting shaft 5 and pushes it into place, which automatically installs the liner onto the clamp and simultaneously installs the next liner. Compared with manually installing the liner clamp, this greatly improves work efficiency and avoids injury to the worker's fingers.
[0060] The support block 25, the first connecting rod 26, the first slider 27, and the spring form an elastic structure, enabling the support block 25 to elastically adjust its position. When the clamp falls onto the two support blocks 25, the two support blocks 25 are in contact. When the mounting shaft 5 moves to the right, the conical surface of the mounting shaft 5 gradually opens the clamp. After the clamp opens, it causes the two support blocks 25 to move away from each other. When the two support blocks 25 move away from each other, the first connecting rod 26 drives the first slider 27 to move upward and compress the spring, so that the notches of the two support blocks 25 can adaptively adjust their position as the clamp opens while maintaining contact with it, keeping the notches in effective contact with the clamp. When the clamp is removed from the support block 25, the first slider 27 moves downward and resets using the spring force, causing the two support blocks 25 to close again.
[0061] The inner wall of the gear ring 67 is equipped with a ratchet, and the bottom outer wall of the mounting plate 68 is equipped with a pawl. The ratchet and pawl cooperate to form a one-way transmission mechanism. When the gear ring 67 rotates counterclockwise, it drives the mounting plate 68 to rotate using the ratchet and pawl mechanism. However, when the gear ring 67 rotates clockwise, it does not drive the mounting plate 68 to rotate. When the slide column 31 moves left or right, it drives the rack 610 to move synchronously. When the rack 610 moves to the right, it drives the gear ring 67 to rotate clockwise. When the rack 610 moves to the left, it drives the gear ring 67 to rotate counterclockwise. Therefore, each time the slide column 31 performs one reciprocating motion, it can indirectly drive the mounting plate 68. During a single rotation of the mounting plate 68, the protrusion 69 on its upper part contacts and compresses the air cylinder 65 once. The compressed air cylinder 65 injects air into the liquid cylinder 62 through the air pipe. The liquid cylinder 62 contains lubricant. After air is injected into the liquid cylinder 62, the positive pressure transports the lubricant inside through the liquid pipe 63 to the atomizing nozzle 64. The atomizing nozzle 64 is arc-shaped and surrounds the mounting shaft 5. Multiple nozzles are arranged in a circumferential array on the atomizing nozzle 64, thus enabling the atomizing nozzle 64 to spray lubricant onto the surface of the mounting shaft 5 through these multiple nozzles. During operation, the mounting shaft 5 moves left and right, reciprocating inside the atomizing nozzle 64. After the sliding column 31 drives the mounting shaft 5 to reciprocate multiple times, the mounting disc 68 rotates once, and the atomizing nozzle 64 sprays lubricant onto the surface of the mounting shaft 5. As the clamp slides along the surface of the mounting shaft 5, it spreads the lubricant evenly. By spraying lubricant onto the surface of the mounting shaft 5, the sliding between the clamp and the mounting shaft 5, as well as between the mounting shaft 5 and the half-sleeve 42, becomes smoother, reducing wear. Furthermore, as the mounting disc 68 rotates once... The number of reciprocating strokes of the slide column 31 required is fixed. In this embodiment, for every twenty clamps installed, the mounting plate 68 rotates once for lubrication. However, multiple spare protrusions 69 are also provided. According to the actual lubrication needs, the operator can install multiple protrusions 69 on the mounting plate 68. For example, after installing two protrusions 69 at equal intervals, each time the mounting plate 68 rotates once, two protrusions 69 will squeeze the air cylinder 65, thereby triggering two lubrications. Therefore, the operator can adjust the lubrication frequency according to the number of protrusions 69 to meet different production needs.
[0062] When the sensing shaft 37 drives the mounting shaft 5 to move to the left and reset, the two half-sleeves 42 are open and not in contact with the mounting shaft 5. The sensing shaft 37 temporarily supports the entire mounting shaft 5 by inserting it into the round hole and drives it to move to the left. After long-term use, this may accelerate the wear or deformation of the sensing shaft 37. Therefore, a support mechanism 7 is provided. The telescopic rod 71 is divided into a fixed section and a telescopic section. When the two half-sleeves 42 move away from each other, the telescopic section of the telescopic rod 71 moves upward and extends through the two third connecting rods 73, so that the telescopic section of the telescopic rod 71 drives the roller 72 at its top to move upward. The roller 72 itself also has elastic deformation capability. After the roller 72 moves upward, it contacts the bottom outer wall of the mounting shaft 5 to temporarily support the mounting shaft 5, so as to share the support pressure of the sensing shaft 37 and reduce the wear of the sensing shaft 37. When the clamp on the mounting shaft 5 contacts the roller 72, the contact part between the roller 72 and the clamp can be concave and deformed, allowing the clamp to pass normally without affecting the movement of the clamp. When the two half sleeves 42 approach and close to each other, the two third connecting rods 73 drive the telescopic rod 71 to retract, so that the roller 72 is separated from the mounting shaft 5, avoiding unnecessary contact.
