Description

Technical Field

[0001] The invention relates to the field of machining equipment, and in particular to an automatic positioning transmission line for a cylinder sleeve. Background Art

[0002] The engine cylinder liner is a key device in the engine. It is usually made of cast iron or aluminum alloy and installed inside the cylinder block. Its function is to provide a smooth working surface so that the piston can move smoothly inside it and reduce friction and wear. At the same time, the cylinder liner also has the function of sealing the cylinder and dissipating heat. The assembly of the cylinder liner is crucial to the working efficiency of the engine.

[0003] Generally speaking, in order to meet processing needs, cylinder liners are placed on conveyor lines in large quantities. For example, the applicant previously disclosed a universal cylinder liner transmission device (Announcement No.: CN219488760U), which positions the cylinder liner at the end of the conveyor chain assembly by setting a positioning assembly to ensure that the final position of the cylinder liner body is unified.

[0004] However, the traditional cylinder liner is a regular cylindrical shape, its cross section is a ring shape, and the inner surface is very smooth to reduce friction and wear. However, with the continuous advancement of existing technology, the cylinder liners currently produced are Figure 1 and Figure 2 As shown, a notch 101 for positioning and fixing is provided on the central through hole of the cylinder liner 1. Since the setting position of the notch 101 is relatively fixed, and generally speaking, in order to meet processing needs, the cylinder liners 1 are manually placed in large quantities on the conveyor line after being processed and formed, so that the notches 101 of different cylinder liners 1 are oriented in different directions, which creates difficulties for the next process. Summary of the invention

[0005] The present invention aims to provide a cylinder liner automatic positioning transmission line to solve the problem of cylinder liners being placed in different positions during the process of conveying cylinder liners in large quantities.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] The automatic positioning transmission line of a cylinder liner comprises a transmission device for batch transmission of the cylinder liner and a control device for integrated control, and also comprises a waiting device arranged in sequence according to the transmission direction of the cylinder liner and a positioning device for correcting the position of the cylinder liner; the waiting device comprises a waiting mounting frame detachably fixedly connected to the transmission device, a first waiting piece and a second waiting piece fixedly installed in sequence on the waiting mounting frame along the transmission direction of the cylinder liner, the first waiting piece and the second waiting piece having one end facing the cylinder liner as a movable end, the movable end of the first waiting piece is a single-headed part which can be inserted into the central through hole of the cylinder liner, and the movable end of the second waiting piece is a double-headed part symmetrically arranged with the movable end of the first waiting piece as the center Head parts, the double-head parts can clamp one end of the outer ring of the cylinder sleeve close to the positioning device; the positioning device includes a positioning component and a transfer component for transferring the cylinder sleeve from the transmission device to the positioning component, the positioning component includes a positioning mounting frame, a rotary positioner fixedly mounted on the positioning mounting frame, the rotary positioner includes a servo motor, a positioning plate fixedly connected to the output end of the servo motor, a positioning pin slidably connected to the positioning plate in the vertical direction, a compression spring sleeved on the positioning pin, and a proximity switch fixedly mounted on the positioning mounting frame, the sensing end of the proximity switch corresponds to the bottom of the positioning pin; the control device is electrically connected to the transmission device, the positioning device, and the waiting device respectively.

[0008] Beneficial effects:

[0009] 1. The positioning device can automatically position batches of cylinder sleeves: through the automatic adjustment and positioning of the positioning device, it is ensured that the notch of each cylinder sleeve is in the same direction, which provides accurate positioning for subsequent processing procedures and improves production efficiency and processing accuracy. Specifically, the positioning device includes a positioning component and a transfer component. The transfer component transfers the cylinder sleeve from the transmission device to the positioning plate on the positioning component. The positioning component includes a servo motor, a positioning plate, a positioning pin, a compression spring and a proximity switch. When the first cylinder sleeve is transferred to the positioning plate, if the top of the positioning pin contacts other parts of the cylinder sleeve next to the notch, the positioning pin will be squeezed by the cylinder sleeve and slide down and enter the sensing range of the proximity switch. After the proximity switch detects the positioning pin, it sends an electrical signal to the control device, and the control device drives the servo motor to drive the positioning plate to rotate until the top of the positioning pin is inserted into the notch in the cylinder sleeve and then drives the cylinder sleeve to rotate a full circle, so that the notch of the cylinder sleeve is in the same direction and faces the initial position before the positioning pin rotates, thus completing the positioning process of the cylinder sleeve.

[0010] 2. The setting of the waiting device is conducive to the efficiency and stability of the positioning process: the waiting device includes a waiting mounting frame, a first waiting piece and a second waiting piece. The movable end of the first waiting piece is a single-headed part, which can be inserted into the central through hole of the cylinder sleeve to intercept the subsequent batches of cylinder sleeves. The movable end of the second waiting piece is a double-headed part symmetrically arranged with the movable end of the first waiting piece as the center, which can clamp one end of the outer ring of the cylinder sleeve close to the positioning device to align the next cylinder sleeve to be positioned. Through the double interception and fixation of the first waiting piece and the second waiting piece, it is ensured that the cylinder sleeve transmitted subsequently will not interfere with the cylinder sleeve being positioned, thereby ensuring the smooth progress of the positioning process. The double-headed part on the second waiting piece clamps the outer ring of the cylinder sleeve and fixes the position of the next cylinder sleeve to be positioned, which provides convenience for the transfer component to grasp the cylinder sleeve and improves the accuracy and efficiency of the transfer component to grasp the cylinder sleeve.

[0011] In summary, this solution solves the problem of inconsistent orientation of the cylinder liner notch through the coordinated work of the positioning device and the waiting device, and realizes the precise positioning of the cylinder liner. The positioning device ensures that the notch of each cylinder liner is in the same direction through automatic adjustment and sliding of the positioning pin, thereby improving production efficiency and processing accuracy. The waiting device prevents interference from subsequent cylinder liners through a two-stage waiting design, provides convenience for the transfer component to grab the cylinder liner, and ensures the efficiency and stability of the entire transmission and positioning process. The implementation of this solution not only improves production efficiency, but also ensures product quality, and has important practical value.

[0012] Preferably, as an improvement, the transmission device includes a base frame and a chain conveyor fixedly mounted on the base frame, the chain conveyor includes a chain driven by a servo motor, the base frame includes side mounting plates fixedly mounted on both sides of the chain plates, a protective cover is arranged on the side mounting plates, and the protective cover is detachably and fixedly connected to the side mounting plates.

[0013] Beneficial effects: The design of the protective cover can prevent operators from accidentally contacting the moving chain plate and cylinder sleeve, improve the safety of the equipment operation process, and prevent some dust and debris from entering the chain plate conveyor, reduce equipment pollution and wear, and extend the service life of the equipment. The protective cover is detachably fixed to the side mounting plate, which is convenient for regular maintenance and cleaning to ensure the long-term stable operation of the equipment.

[0014] Preferably, as an improvement, the first waiting piece and the second waiting piece both include a cylinder and a plug detachably fixedly connected to the movable end of the cylinder, the single-headed part on the first waiting piece is a plug, and the double-headed part on the second waiting piece is two plugs symmetrically arranged with the movable end of the first waiting piece as the center.

[0015] Beneficial effects: The use of the cylinder can achieve precise control of the plug, ensuring that the plug can be accurately inserted into or stuck in the cylinder sleeve. At the same time, the rapid response of the cylinder also improves the working efficiency of the waiting device, which is beneficial to improve the timeliness of the switching of the cylinder sleeve between the waiting state and the moving state.

[0016] Preferably, as an improvement, the control device includes a control box fixedly arranged at the bottom of the transmission device and a controller fixedly installed in the control box, and the controller is electrically connected to the servo motor in the transmission device, the proximity switch and servo motor in the positioning device, and the cylinder in the waiting device, respectively.

[0017] Beneficial effects: The setting of the control box and controller realizes the centralized control of the whole system, simplifies the operation process, improves the coordination and reliability of the system, and ensures the stable operation of the system by real-time monitoring and adjusting the working status of each component.

[0018] Preferably, as an improvement, the positioning device also includes a conical positioning plate fixedly arranged at the end of the chain conveyor and an abutment joint fixedly arranged at the center of the conical positioning plate, and a guide bar is suspended above the chain plate to provide guidance for the transmission of the cylinder liner, and one end of the guide bar close to the positioning device does not extend to the position of the abutment joint.

[0019] Beneficial effects: The design of the conical positioning plate and the abutment joint can guide the cylinder sleeve accurately into the grasping range of the transfer assembly, ensure the accurate position of the cylinder sleeve, and ensure that the cylinder sleeve is transferred from the chain plate to the positioning assembly in a timely and efficient manner.

[0020] Preferably, as an improvement, a plurality of magnets for attracting the bottom surface of the cylinder sleeve are arranged on the positioning mounting frame along the outer circumference of the positioning plate.

[0021] Beneficial effect: The magnet can attract the bottom surface of the cylinder sleeve to ensure the stable fixation of the cylinder sleeve on the positioning plate, prevent displacement caused by vibration or external force from affecting the accuracy of the positioning process, thereby improving the positioning accuracy.

[0022] Preferably, as an improvement, the transfer assembly includes a transfer mounting frame fixedly mounted on the side of the transmission device, an electric slide fixedly mounted on the transfer mounting frame, and an electric chuck fixedly mounted on the electric slide, wherein the movable end of the electric chuck can be inserted into the central through hole of the cylinder sleeve and fixedly engaged with the inner wall of the cylinder sleeve.

[0023] Beneficial effect: The combination of the electric slide and the electric chuck can realize the precise transfer of the cylinder sleeve and ensure the smooth transition of the cylinder sleeve from the transmission device to the positioning device. The movable end of the electric chuck can be inserted into the central through hole of the cylinder sleeve and fixed with the inner wall of the cylinder sleeve, which improves the efficiency and reliability of the transfer.

[0024] Preferably, as an improvement, a plurality of mounting grooves are fixedly provided on the top of the positioning mounting frame, the magnet is embedded and fixed in the mounting groove, and the side of the magnet close to the cylinder sleeve is lower than the top surface of the mounting frame, so that the magnet will not contact the cylinder sleeve when the cylinder sleeve is installed on the positioning plate.

[0025] Beneficial effect: The side of the magnet close to the cylinder sleeve is limited to be lower than the top surface of the mounting frame, so that the magnet will not contact the cylinder sleeve when the cylinder sleeve is installed on the positioning plate. This is to ensure that the magnet has a certain attraction to the cylinder sleeve and does not affect the rotation process of the cylinder sleeve driven by the servo motor and the positioning plate, ensuring that the positioning process can be smoothly implemented. At the same time, the embedded fixing method makes the magnet more stable and not easy to fall off, ensuring the long-term and effective use of the magnet. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is further described in detail through specific implementation methods:

[0036] The figure marks in the drawings of the specification include: cylinder sleeve 1, notch 101, transmission device 2, base frame 201, chain plate 202, side mounting plate 203, protective cover 204, guide strip 205, mounting seat 206, waiting device 3, waiting mounting frame 301, first waiting member 302, second waiting member 303, plug 304, proximity sensor 305, positioning device 4, positioning assembly 41, positioning mounting frame 411, positioning plate 412, positioning pin 413, compression spring 414, proximity switch 415, magnet 416, transfer assembly 42, transfer mounting frame 421, electric slide 422, electric chuck 423, conical positioning plate 43, abutment 44, control device 5.

[0037] Cylinder liner automatic positioning transmission line, combined with Figure 1-Figure 9 As shown, it includes a transmission device 2 for batch transmission of cylinder sleeves 1, a waiting device 3 for distributing cylinder sleeves 1, a positioning device 4 for correcting the position of cylinder sleeves 1, and a control device 5 for integrated control. The positioning device 4 is located at the output end of the transmission cylinder sleeves 1, and the waiting device 3 is located near the positioning device 4. The working principle of this scheme is to place a batch of cylinder sleeves 1 on the transmission device 2, and the cylinder sleeves 1 are transferred from the transmission device 2 to the positioning device 4 for position correction. In the process of correcting the cylinder sleeves 1, the waiting device 3 will temporarily fix the next cylinder sleeve 1 to be corrected to achieve the purpose of distribution.

[0038] The transmission device 2 is as follows Figure 3 As shown, it includes a frame and a chain conveyor fixedly installed on the frame, the chain conveyor includes a chain 202 driven by a servo motor, the frame includes a base frame 201 and side mounting plates 203 located on both sides of the chain 202, and the side mounting plates 203 are fixed to the top of the base frame 201 by screws; a protective cover 204 is set on the top of the side mounting plate 203 in a screw-fixed manner to prevent people from approaching or touching the moving parts on the conveyor line, thereby reducing the risk of accidental injury. A guide bar 205 is arranged above the chain plate 202. The guide bar 205 is arranged to avoid excessive deviation in the placement position of the cylinder sleeve 1, which would cause inconvenience to the allocation work of the waiting device 3. The mounting seat 206 is fixed by screws on the frame at the input end of the chain conveyor. A key groove perpendicular to the movement direction of the chain plate 202 is opened on the mounting seat 206. One end of the guide bar 205 is detachably connected to the mounting seat 206 in the above-mentioned key groove by screw fixing, and the other end is connected to the waiting device 3. The screws on the mounting seat 206 are removed and the guide bar 205 is slid along the key groove to adjust the distance between the two relative guide bars 205, so as to adapt to the transmission of cylinder sleeves 1 of different specifications, and the scope of application is wider.

[0039] Waiting device 3 Figure 4As shown, it includes a standby mounting frame 301 mounted on the chain plate 202, a first standby member 302 and a second standby member 303 fixedly mounted on the standby mounting frame 301 in sequence along the transmission direction of the cylinder sleeve 1, and a proximity sensor 305 for identifying the cylinder sleeve 1. The standby mounting frame 301 includes a top seat and a pillar fixed to the bottom of the top seat, a mounting bar is provided at the bottom of the pillar, and the mounting bar is fixed to the side mounting plate 203 with screws; in order to further ensure stability, pillars are provided at the four corners of the top seat in this embodiment, and the pillars located on the same side of the side mounting plate 203 are fixed together on a mounting bar. The proximity sensor 305 is installed on one of the mounting bars by screws. On the basis that one end of the guide bar 205 is connected to the mounting seat 206, a mounting bar is also fixed on the pillar located on the non-same side of the side mounting plate 203, and a key slot is provided on the mounting bar. The other end of the guide bar 205 is fixedly connected to the mounting bar in the key slot by screw fixing, so that the guide bar 205 is suspended above the chain plate 202, and the installation spacing of the guide bar 205 can also be appropriately adjusted to adapt to the transportation of cylinder sleeves 1 of different specifications. The movable end of the first waiting part 302 is a single-head part, and the movable end of the second waiting part 303 is a double-head part. The first waiting piece 302 and the second waiting piece 303 both include a cylinder and a plug 304 fixedly connected to the movable end of the cylinder. The single-headed part on the first waiting piece 302 is a plug 304, which can be inserted into the central through hole of the cylinder liner 1; the double-headed part on the second waiting piece 303 is two plugs 304 symmetrically arranged with the plug 304 on the first waiting piece 302 as the center, so that the second waiting piece 303 is an inverted Y shape as a whole, so that the two plugs 304 on the second waiting piece 303 can clamp the end of the outer ring of the cylinder liner 1 close to the positioning device 4.

[0040] Positioning device 4 Figure 3 , Figure 5-Figure 9 As shown, it includes a positioning component 41, a transfer component 42 for transferring the cylinder sleeve 1 from the chain plate 202 to the positioning component 41, two conical positioning plates 43 fixedly arranged at the output end of the chain plate conveyor and arranged opposite to each other, and a butt joint 44 fixedly arranged at the center of the two conical positioning plates 43.

[0041] Transfer assembly 42 such as Figure 3As shown, it includes a transfer mounting frame 421 fixedly mounted on the side of the transmission device 2, an electric slide 422 fixedly mounted on the transfer mounting frame 421, and an electric chuck 423 fixedly mounted on the electric slide 422. The movable end of the electric chuck 423 can be inserted into the central through hole of the cylinder sleeve 1 and fixedly engaged with the inner wall of the cylinder sleeve 1. It is worth mentioning that the guide bar 205 does not extend to the end of the transmission device 2, that is, it does not cover the entire chain plate 202, but only extends to the vicinity of the waiting device 3. The purpose of this is to avoid interfering with the transfer component 42 grabbing the cylinder sleeve 1. For example, for a thinner cylinder sleeve 1, its height may be close to or even lower than the installation height of the guide bar 205. In this way, when the electric chuck 423 reaches down to grab the cylinder sleeve 1, the surface of the electric chuck 423 is easy to touch the guide bar 205.

[0042] Positioning component 41 Figure 5 As shown, it includes a positioning mounting frame 411 and a rotary positioner fixedly mounted on the positioning mounting frame 411. The rotary positioner includes a servo motor, a positioning plate 412 fixedly connected to the output end of the servo motor, a positioning pin 413 slidably connected to the positioning plate 412 in the vertical direction, a compression spring 414 sleeved on the positioning pin 413, and a proximity switch 415 fixedly mounted on the positioning mounting frame 411. Specifically, the positioning mounting frame 411 as a support member of the positioning assembly 41 is a box structure with a hollow middle portion. The panel located at the bottom of the positioning mounting frame 411 is fixedly connected to the base frame 201 and is used to fix the servo motor that drives the positioning plate 412. The panel (top plate) located at the top of the positioning mounting frame 411 is used to fix the positioning plate 412. Specifically, a through hole is opened in the center of the top plate, and the output end of the servo motor extends out of the through hole and is fixedly connected to the positioning plate 412. A groove is provided on the top plate adjacent to the through hole, and a proximity switch 415 is fixedly installed in the groove. The sensing end of the proximity switch 415 corresponds to the bottom of the positioning pin 413. When the top end of the positioning pin 413 is inserted into the notch 101 in the cylinder sleeve 1, the bottom of the positioning pin 413 does not enter the sensing range of the proximity switch 415. At this time, the positioning plate 412 is in a stationary state. However, when the top end of the positioning pin 413 contacts other parts of the cylinder sleeve 1 next to the notch 101, the positioning pin 413 is squeezed by the cylinder sleeve 1 and slides downward and enters the sensing range of the proximity switch 415. At this time, the proximity switch 415 sends an electrical signal to the control device 5 and drives the servo motor to drive the positioning plate 412 to rotate until the top end of the positioning pin 413 is inserted into the notch 101 in the cylinder sleeve 1 to complete the positioning process of the cylinder sleeve 1.

[0043] like Figure 7 and Figure 8As shown, six magnets 416 for attracting the bottom surface of the cylinder sleeve 1 are arranged on the positioning mounting frame 411 along the outer circumference of the positioning plate 412. Five mounting grooves are arranged circumferentially on the top of the positioning mounting frame 411, and the magnets 416 are embedded and fixed in the mounting grooves. It is worth noting that the side of the magnet 416 close to the cylinder sleeve 1 is lower than the top surface of the mounting frame, so that the magnet 416 does not really contact the cylinder sleeve 1. The role of the magnet 416 is only to enhance the stability of the cylinder sleeve 1 parts during the positioning process, to prevent the cylinder sleeve 1 from tilting during the rotation process with the positioning plate 412, thereby affecting the accuracy of the positioning notch 101. If the magnet 416 and the cylinder sleeve 1 are really in contact, it will be unfavorable for the positioning pin 413 to drive the rotation process of the cylinder sleeve 1, thereby affecting the smooth progress of the positioning process of the cylinder sleeve 1.

[0044] The control device 5 includes a control box fixedly arranged at the bottom of the base frame 201 and a controller fixedly installed in the control box. The controller is a PLC or a single-chip microcomputer. In this embodiment, the controller is a PLC. The controller is electrically connected to the servo motor in the transmission device 2, the proximity switch 415 and the servo motor in the positioning device 4, and the cylinder in the waiting device 3.

[0045] The specific implementation process is as follows:

[0046] When in use, the cylinder sleeve 1 is first placed on the chain plate 202 in sequence by means of a manipulator or manual placement, specifically between the two guide bars 205, so that the cylinder sleeve 1 is transported to the bottom of the waiting device 3 along the guide bar 205 in sequence. The waiting device 3 can realize the two-level waiting of the cylinder sleeve 1 by providing the first waiting member 302 and the second waiting member 303. For the convenience of description, the cylinder sleeve 1 being positioned on the positioning assembly 41 is named the first cylinder sleeve, and the next cylinder sleeve waiting for positioning after the first cylinder sleeve is named the second cylinder sleeve, and so on. The third cylinder sleeve, the fourth cylinder sleeve, and so on are next. The function of the first waiting member 302 is to intercept and fix the third cylinder sleeve and all cylinder sleeves after the third cylinder sleeve outside the second waiting member 303. The function of the second waiting piece 303 is to intercept and fix the second cylinder liner separately, and at the same time rely on the double-headed parts on the second waiting piece 303 to make a preliminary correction to the position of the second waiting piece 303, so as to facilitate the subsequent transfer component 42 to grasp the inner wall of the central through hole of the second cylinder liner to achieve clamping and fixing. Prior to this, the first cylinder liner is undergoing a positioning process on the positioning component 41. The specific steps of the positioning process are: the transfer component 42 first transfers the first cylinder sleeve to the positioning plate 412, and the first cylinder sleeve cover is arranged on the positioning plate 412. If the top end of the positioning pin 413 contacts the other part of the cylinder sleeve 1 next to the notch 101 at this time, the positioning pin 413 will be squeezed by the cylinder sleeve 1 to slide downward and enter the sensing range of the proximity switch 415, so that the proximity switch 415 sends an electrical signal to the control device 5. After receiving the electrical signal, the control device 5 will drive the servo motor to drive the positioning plate 412 to rotate until the top end of the positioning pin 413 is inserted into the notch 101 in the cylinder sleeve 1. After the positioning pin 413 is inserted into the notch 101, it will drive the cylinder sleeve 1 to continue to rotate, that is, the number of rotations of the servo motor is controlled by the program, so that the positioning plate 412 is fixedly rotated for a full circle each time it is driven, and the notch 101 of the cylinder sleeve 1 can eventually face the initial position of the positioning pin 413. Finally, the first cylinder sleeve is transferred to the next processing step by a manipulator independent of the transmission line to complete the entire positioning process. After one positioning process is completed, the second waiting member 303 will release the fixing restriction on the second cylinder sleeve, so that the second cylinder sleeve is moved by the running chain plate 202 to the end of the transmission device 2, that is, the position of the conical positioning plate 43 and the abutment head 44, and then the transfer assembly 42 transfers the second cylinder sleeve to the positioning plate 412 to start positioning the second cylinder sleeve. At the same time, the first waiting member 302 will also release the fixing restriction on the third cylinder sleeve, so that the third cylinder sleeve moves to the original position of the second cylinder sleeve and is restricted by the second waiting member 303.

[0047] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
