Description

Technical Field

[0001] The invention belongs to the technical field of casing transfer, and in particular relates to an automatic casing transfer device. Background Art

[0002] PI casing machine is a kind of equipment specially used for making pipe casings. After the pipe casings are processed and formed, they need to be transported one by one. In this process, in order to avoid deformation of the pipe casing due to long-term clamping and other reasons, special casing transplanting equipment is needed to transport the casing and connect the pipe casing to the specified material.

[0003] Conventional casing transfer devices are mainly used for clamping and pushing casings at the same time. They are generally used in conjunction with electric grippers and electric push rods. The specific implementation method is that the electric grippers clamp the casing and then push the electric grippers to move through the electric push rods to achieve the casing transfer process. Due to the limited stroke of the electric push rods, multiple electric grippers and electric push rods are required, resulting in high cost of use. At the same time, it must wait for the pushing of a single casing to be completed before the clamping process of the next casing can be carried out, and the work efficiency is low.

[0004] At the same time, during the pushing process of the casing, multiple electric push rods must be pushed at the same time, with the same displacement, and they must be reset at the same time after the pushing is completed. The whole control process is relatively cumbersome. At the same time, the frequent extension and shortening of the electric push rods will also cause them to overheat, which will lead to a decrease in service life and an increase in failure rate. Summary of the invention

[0005] The object of the present invention is to provide an automatic transfer device for casing to solve the problems mentioned in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automated transfer device for casing, comprising a cam divider, wherein a machine base is installed on both the front and rear sides of the top end of the cam divider, the number of the machine bases is four in total, and each two are symmetrically arranged at the top end of the cam divider, the top end of the machine base is provided with a bottom transverse slot, and the inside of the bottom transverse slot is movably connected with a clamping assembly, a top frame is provided above the clamping assembly, and the left and right sides of the bottom end of the top frame are provided with a top transverse slot, and the bottom end of the top transverse slot is movably connected with the clamping assembly, an extension frame is fixedly installed at one end of the two top frames that are relatively close to each other, and a longitudinal guide rail is fixedly installed at the bottom end of the extension frame, a linkage assembly is installed at a position between the top ends of the two clamping assemblies, a push tube assembly is movably installed inside the linkage assembly, and the side of the push tube assembly close to the longitudinal guide rail is movably connected to the longitudinal guide rail, and a return spring is fixedly installed at the top of the inner cavity of the longitudinal guide rail, and the bottom end of the return spring is connected to one end of the push tube assembly.

[0007] Among them, the single rotation angle of the cam divider is one hundred and eighty degrees, and the left and right sides of the top of the cam divider correspond to the receiving end and the discharging end of the sleeve respectively, that is, the left end of the cam divider is used for clamping the sleeve, and the right end of the cam divider is used for moving the sleeve. After completing the positioning of the two ends, the sleeve can be automatically transferred.

[0008] As a further technical solution of the present invention, the clamping assembly includes a frame, a lower guide block is fixedly installed on the bottom end of the frame, the frame is movably connected between the lower guide block and the bottom transverse slot, a cylinder is fixedly installed on one side of the inner cavity of the bottom transverse slot, and the output end of the cylinder is connected to one side of the lower guide block.

[0009] As a further technical solution of the present invention, an upper guide block is fixedly installed on the top of the frame, and the upper guide block is movably connected to the top horizontal slot. A clamping block is fixedly installed in the middle of the frame, and two relatively close ends of the clamping blocks are provided with mounting grooves, and balls are movably installed inside the mounting grooves.

[0010] When it is necessary to clamp the sleeve, the sleeve can be kept in the position between the two clamping assemblies. At this time, the cylinder can be turned on, and the cylinder will extend and push the lower guide block to move relative to the bottom transverse slot. At this time, the two frames can be displaced synchronously and in a relatively close direction, and drive the two clamping blocks to approach each other, and the upper guide block at the top will be displaced relative to the top transverse slot until the balls on one side of the two clamping blocks contact the two sides of the sleeve. At this time, the clamping process of the sleeve can be completed.

[0011] As a further technical solution of the present invention, the linkage assembly includes a movable seat arranged between two frames, and a first fixed seat is fixedly installed on the left and right sides of the top of the movable seat, and the end of the first fixed seat away from the movable seat is movably connected to a linkage rod through a rotating shaft, and the end of the linkage rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0012] As a further technical solution of the present invention, the side of the second fixing seat away from the linkage rod is connected to the inner side surface of the frame close to the top, and a locking hole is opened in the middle of the side of the first fixing seat close to the longitudinal guide rail, and the locking hole is movably connected to the push tube assembly.

[0013] As a further technical solution of the present invention, a through groove for installing the push tube assembly is opened in the middle of the movable seat, and mounting seats are installed on the left and right sides of the bottom end of the movable seat. A main shaft is movably connected between the two mounting seats, and the outer side surface of the main shaft is fixedly sleeved with the push tube assembly, and the main shaft rotates relative to the mounting seat and is located directly below the through groove.

[0014] When the two frames are relatively close, the distance between the two frames decreases accordingly. At this time, a thrust can be applied to the two linkage rods, which then deflect obliquely downward and apply downward pressure to the movable seat. The movable seat then moves downward, and the locking hole and the push tube assembly maintain a connection relationship in the initial state. When the movable seat moves downward, the main shaft can be driven downward synchronously, and the push tube assembly can be driven downward until the bottom end of the push tube assembly contacts the top end of the outer side surface of the sleeve, completing the pre-pushing process, until the clamping assembly holding the sleeve moves to the right end of the cam divider, the push tube assembly can be operated to complete the pushing process of the sleeve, and at this time, the left side of the cam divider can synchronously clamp the sleeve, completing clamping and pushing at the same time.

[0015] By utilizing the clamping process of the sleeve, that is, utilizing the clamping process of the clamping component to act on the linkage component, the movable seat is automatically moved downward, and it is acted on the tube pushing component, so that the device does not need to be equipped with multiple electric push rods, and the sleeve can be automatically pushed after the clamping is completed. During the entire pushing process, there is no need to set up multiple electric clamps and multiple electric push rods, and the sleeve can be clamped and pushed simultaneously, which effectively shortens the waiting time, reduces the cost of use, and improves work efficiency.

[0016] As a further technical solution of the present invention, the push tube assembly includes a guide roller located inside the through groove, the middle part of the guide roller is fixedly sleeved with the outer side surface of the main shaft, the push tube assembly also includes a driven gear located on the left and right sides of the guide roller, the driven gear is fixedly sleeved with the main shaft, the guide roller and the driven gear are coaxially arranged, and the top end of the driven gear is meshed and connected with a driving gear.

[0017] As a further technical solution of the present invention, an installation shaft is fixedly connected between the two driving gears, and locking frames are movably sleeved on the left and right ends of the installation shaft and fixed above the movable seat through the locking frames, and the left and right sides of the installation shaft are fixedly connected with a first connecting rod.

[0018] As a further technical solution of the present invention, one end of the first connecting rod away from the mounting shaft is movably connected to the second connecting rod through a rotating shaft, and a connecting shaft is provided on one side of the two second connecting rods away from the first connecting rod, and the left and right ends of the connecting shaft are movably connected to the two second connecting rods respectively, and the middle part of the connecting shaft is movably connected to a longitudinal guide block

[0019] As a further technical solution of the present invention, the longitudinal guide block is movably connected to the longitudinal guide rail, the bottom end of the reset spring is connected to the top end of the longitudinal guide block, and a micro push rod is installed on the side of the longitudinal guide block close to the movable seat. The micro push rod is located directly in front of the locking hole, and the output end diameter of the micro push rod is adapted to the diameter of the locking hole, and is movably connected to the locking hole.

[0020] When clamping, the micro push rod is in the initial state, that is, the micro push rod maintains the clamping state with the locking hole. When the movable seat moves down, the guide roller can be driven downward synchronously until the outer side surface of the guide roller contacts the outer side surface of the sleeve. At the same time, when the movable seat moves down, the longitudinal guide block can be driven downward synchronously. At this time, the reset spring can be stretched, and the second connecting rod swings accordingly, and drives the first connecting rod to rotate. At this time, the mounting shaft rotates synchronously and drives the driving gear to rotate. At this time, the driven gear in the meshing state at the bottom can rotate synchronously, and finally drives the guide roller to rotate until the guide roller contacts the outer side surface of the sleeve. At this time, the movable seat stops moving downward, and the longitudinal guide block stops moving downward, and the guide roller stops rotating, completing the energy storage process.

[0021] When it is necessary to push the sleeve, the sleeve can be aligned with the discharge end, and the micro push rod can be controlled to shorten to release the clamping connection between it and the locking hole. At this time, the device can maintain the clamping state of the sleeve, and after the micro push rod releases the limit, the reset spring can automatically reset, and drive the longitudinal guide block to rise, and drive the second connecting rod to swing in the opposite direction, and at the same time drive the first connecting rod to rotate in the opposite direction. At this time, the driving gear rotates in the opposite direction, and finally drives the guide roller to rotate through the driven gear. At this time, the friction force can be used to push the sleeve below to move, and the pipe pushing operation is completed.

[0022] By utilizing the action when the casing is clamped, that is, when the casing is clamped, the relative proximity of the two frames drives the movable seat to move downward, and energy is stored through the pipe pushing assembly, and the energy is released when pushing the pipe, so the pipe pushing operation is realized instantly. The whole process does not use multiple electric push rods, but energy is stored in the clamping process, and no additional power is required for the pipe pushing operation, thereby avoiding overheating and reduced life caused by frequent extension and shortening of the electric push rods of traditional devices, and reducing its failure rate.

[0023] At the same time, in the process of clamping the sleeve, after the clamping of the sleeve is completed, the top of the outer side surface of the sleeve is in contact with the outer side surface of the guide roller, and the two ends of the sleeve are in contact with the two balls. At this time, the sleeve can be clamped between three points, and when pushing the tube, the balls can always keep in contact with both sides of the sleeve, and the guide roller also keeps in contact with the top of the outer side surface of the sleeve. When pushing the tube, the rolling of the guide roller drives the sleeve to move, and the balls roll accordingly, and the sleeve is moved out smoothly.

[0024] By reusing the copper tube clamping and sleeve pushing process, that is, always maintaining three-point support during the clamping and pushing process, the stability of the sleeve during clamping and pushing is ensured, and its smooth displacement is ensured. At the same time, when the sleeve is pushed, due to the rolling of the guide roller and the ball, the sliding friction during traditional tube pushing is converted into rolling friction, ensuring that the sleeve will not be scratched when it moves. This not only improves the stability of the sleeve during transfer, but also reduces the scratch rate of the sleeve.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The present invention utilizes the clamping process of the sleeve, that is, utilizes the clamping process of the clamping component to act on the linkage component, realizes the automatic downward movement of the movable seat, and acts on the tube pushing component, so that the device does not need to be provided with multiple electric push rods, and can automatically push the sleeve after completing the clamping. During the entire pushing process, it is not necessary to set up multiple electric clamps and multiple electric push rods, and the sleeve can be clamped and pushed synchronously, which effectively shortens the waiting time, reduces the use cost, and improves the work efficiency.

[0027] 2. The present invention utilizes the action during the clamping of the casing, that is, when the casing is clamped, the relative proximity of the two frames drives the movable seat to move downward, and completes energy storage through the tube pushing assembly, and releases energy when pushing the tube, and instantly realizes the tube pushing operation. The whole process does not use multiple electric push rods, but stores energy for the clamping process, and does not require additional power for the tube pushing operation, thereby avoiding overheating and reduced life caused by frequent extension and shortening of the electric push rod of the traditional device, and reducing its failure rate.

[0028] 3. The present invention reuses the process of copper tube clamping and sleeve pushing, that is, three-point support is always maintained during the clamping and pushing process, thereby ensuring the stability of the sleeve during clamping and pushing, and ensuring its smooth displacement. At the same time, when the sleeve is pushed, due to the rolling of the guide roller and the ball, the sliding friction during traditional tube pushing is converted into rolling friction, ensuring that the sleeve will not be scratched when it moves, which not only improves the stability of the sleeve during transfer, but also reduces the scratch rate of the sleeve.

[0045] Embodiment: When the two frames 401 are relatively close, the distance between the two frames 401 decreases accordingly. At this time, a thrust can be applied to the two linkage rods 804. At this time, the two linkage rods 804 deflect obliquely downward and apply downward pressure to the movable seat 801. At this time, the movable seat 801 moves downward accordingly. At the same time, the locking hole 805 and the push tube assembly 11 maintain a connection relationship in the initial state. When the movable seat 801 moves downward, the main shaft 807 can be driven downward synchronously, and the push tube assembly 11 can be driven downward until the bottom end of the push tube assembly 11 contacts the top of the outer side surface of the sleeve, completing the pre-pushing process, until the clamping assembly 4 holding the sleeve moves to the right end of the cam divider 1, the push tube assembly 11 can be operated to complete the pushing process of the sleeve, and at this time, the left side of the cam divider 1 can synchronously clamp the sleeve, completing the clamping and pushing at the same time.

[0046] By utilizing the clamping process of the sleeve, that is, utilizing the clamping process of the clamping component 4 to act on the linkage component 8, the movable seat 801 is automatically moved downward, and it is acted on the tube pushing component 11, so that the device does not need to be equipped with multiple electric push rods, and the sleeve can be automatically pushed after the clamping is completed. During the entire pushing process, there is no need to set up multiple electric clamps and multiple electric push rods, and the sleeve can be clamped and pushed simultaneously, which effectively shortens the waiting time, reduces the cost of use, and improves work efficiency.

[0047] like Figure 3 and Figure 5 as well as Figure 8 and Fig. 9As shown, the push tube assembly 11 includes a guide roller 111 located inside the through groove, the middle part of the guide roller 111 is fixedly sleeved with the outer side surface of the main shaft 807, the push tube assembly 11 also includes a driven gear 112 located on the left and right sides of the guide roller 111, the driven gear 112 is fixedly sleeved with the main shaft 807, the guide roller 111 and the driven gear 112 are coaxially arranged, the top of the driven gear 112 is meshed and connected with a driving gear 113, a mounting shaft 114 is fixedly connected between the two driving gears 113, the left and right ends of the mounting shaft 114 are movably sleeved with locking frames, and are fixed to the top of the movable seat 801 through the locking frames, the left and right sides of the mounting shaft 114 are fixedly connected with a first connecting rod 115, and the first connecting rod 115 is away from the mounting shaft 11 One end of the second connecting rod 116 is movably connected to the second connecting rod 116 through a rotating shaft, and a connecting shaft 117 is provided on the side of the two second connecting rods 116 away from the first connecting rod 115. The left and right ends of the connecting shaft 117 are movably connected to the two second connecting rods 116 respectively, and the middle part of the connecting shaft 117 is movably connected to a longitudinal guide block 118, and the longitudinal guide block 118 is movably engaged with the longitudinal guide rail 9. The bottom end of the return spring 10 is connected to the top end of the longitudinal guide block 118, and a micro push rod 119 is installed on the side of the longitudinal guide block 118 close to the movable seat 801. The micro push rod 119 is located just in front of the locking hole 805, and the output end diameter of the micro push rod 119 is adapted to the diameter of the locking hole 805, and is movably engaged with the locking hole 805.

[0048] Embodiment: When clamping, the micro push rod 119 is in the initial state, that is, the micro push rod 119 maintains the clamping state with the locking hole 805. When the movable seat 801 moves down, the guide roller 111 can be synchronously driven to move down until the outer side surface of the guide roller 111 contacts the outer side surface of the sleeve. At the same time, when the movable seat 801 moves down, the longitudinal guide block 118 can be synchronously driven to move down. At this time, the reset spring 10 can be stretched, and the second connecting rod 116 swings accordingly, and drives the first connecting rod 115 to rotate. At this time, the mounting shaft 114 rotates synchronously and drives the driving gear 113 to rotate. At this time, the driven gear 112 in the meshing state at the bottom can rotate synchronously, and finally drives the guide roller 111 to rotate until the guide roller 111 contacts the outer side surface of the sleeve. At this time, the movable seat 801 stops moving down, and the longitudinal guide block 118 stops moving down, and the guide roller 111 stops rotating, completing the energy storage process;

[0049] When it is necessary to push the sleeve, the sleeve can be aligned with the discharge end, and the micro push rod 119 can be controlled to shorten to release the clamping connection between it and the locking hole 805. At this time, the device can maintain the clamping state of the sleeve, and after the micro push rod 119 releases the limit, the reset spring 10 can automatically reset, and drive the longitudinal guide block 118 to rise, and drive the second connecting rod 116 to swing in the opposite direction, and at the same time drive the first connecting rod 115 to rotate in the opposite direction. At this time, the driving gear 113 rotates in the opposite direction, and finally drives the guide roller 111 to rotate through the driven gear 112. At this time, the friction force can be used to push the sleeve below to move, and the pipe pushing operation is completed.

[0050] By utilizing the action when the casing is clamped, that is, when the casing is clamped, the relative proximity of the two frames 401 drives the movable seat 801 to move downward, and energy is stored through the tube pushing assembly 11, and the tube pushing operation is instantly realized by releasing energy when pushing the tube. The whole process does not use multiple electric push rods, but energy is stored in the clamping process, and no additional power is required for the tube pushing operation, thereby avoiding overheating and reduced life caused by frequent extension and shortening of the electric push rods of traditional devices, and reducing its failure rate.

[0051] At the same time, in the process of clamping the sleeve, after the clamping of the sleeve is completed, the top of the outer side surface of the sleeve is in contact with the outer side surface of the guide roller 111, and the two ends of the sleeve are in contact with the two balls 406. At this time, the sleeve can be clamped between three points, and when pushing the tube, the balls 406 can always keep in contact with both sides of the sleeve, and the guide roller 111 also keeps the top of the outer side surface of the sleeve in contact. When pushing the tube, the rolling of the guide roller 111 drives the sleeve to move, and the balls 406 roll accordingly and smoothly move the sleeve out.

[0052] By reusing the copper tube clamping and sleeve pushing process, that is, always maintaining three-point support during the clamping and pushing process, the stability of the sleeve during clamping and pushing is ensured, and its smooth displacement is ensured. At the same time, when the sleeve is pushed, due to the rolling of the guide roller 111 and the ball 406, the sliding friction during traditional tube pushing is converted into rolling friction, ensuring that the sleeve will not be scratched when it moves. This not only improves the stability of the sleeve during transfer, but also reduces the scratch rate of the sleeve.

[0053] Working principle and usage process:

[0054] When the sleeve needs to be clamped, the sleeve can be kept in the position between the two clamping components 4, and the cylinder 404 can be turned on. At this time, the cylinder 404 extends and pushes the lower guide block 403 to move relative to the bottom transverse slot 3. At this time, the two racks 401 can be displaced synchronously and in a relatively close direction, and drive the two clamping blocks 405 to approach each other, and the upper guide block 402 at the top is displaced relative to the top transverse slot 6, until the balls 406 on one side of the two clamping blocks 405 contact the two sides of the sleeve, and the clamping process of the sleeve can be completed at this time;

[0055] When the two frames 401 are relatively close to each other, the distance between the two frames 401 decreases accordingly, and at this time, a thrust can be applied to the two linkage rods 804, and at this time, the two linkage rods 804 deflect obliquely downward and apply downward pressure to the movable seat 801, and at this time, the movable seat 801 moves downward accordingly, and at the same time, the locking hole 805 and the push tube assembly 11 maintain a connection relationship in the initial state. When the movable seat 801 moves downward, the main shaft 807 can be synchronously driven to move downward, and the push tube assembly 11 can be driven to move downward until the bottom end of the push tube assembly 11 contacts the top of the outer side surface of the sleeve, completing the pre-pushing process, until the clamping assembly 4 holding the sleeve moves to the right end of the cam divider 1, the push tube assembly 11 can be operated to complete the pushing process of the sleeve, and at this time, the left side of the cam divider 1 can synchronously clamp the sleeve, completing the clamping and pushing at the same time;

[0056] When clamping, the micro push rod 119 is in the initial state, that is, the micro push rod 119 maintains the clamping state with the locking hole 805. When the movable seat 801 moves down, the guide roller 111 can be synchronously driven to move down until the outer side surface of the guide roller 111 contacts the outer side surface of the sleeve. At the same time, when the movable seat 801 moves down, the longitudinal guide block 118 can be synchronously driven to move down. At this time, the reset spring 10 can be stretched, and the second connecting rod 116 swings accordingly, and drives the first connecting rod 115 to rotate. At this time, the mounting shaft 114 rotates synchronously and drives the driving gear 113 to rotate. At this time, the driven gear 112 in the meshing state at the bottom can rotate synchronously, and finally drives the guide roller 111 to rotate until the guide roller 111 contacts the outer side surface of the sleeve. At this time, the movable seat 801 stops moving down, and the longitudinal guide block 118 stops moving down, and the guide roller 111 stops rotating, completing the energy storage process;

[0057] When the sleeve needs to be pushed, the sleeve can be aligned with the discharge end, and the micro push rod 119 can be controlled to shorten to release the clamping connection between it and the locking hole 805. At this time, the device can maintain the clamping state of the sleeve, and after the micro push rod 119 releases the limit, the reset spring 10 can automatically reset, and drive the longitudinal guide block 118 to rise, and drive the second connecting rod 116 to swing in the opposite direction, and drive the first connecting rod 115 to rotate in the opposite direction. At this time, the driving gear 113 rotates in the opposite direction, and finally drives the guide roller 111 to rotate through the driven gear 112. At this time, the friction force can be used to push the sleeve below to move, and the pipe pushing operation is completed;

[0058] At the same time, in the process of clamping the sleeve, after the clamping of the sleeve is completed, the top of the outer side surface of the sleeve is in contact with the outer side surface of the guide roller 111, and the two ends of the sleeve are in contact with the two balls 406. At this time, the sleeve can be clamped between three points, and when pushing the tube, the balls 406 can always keep in contact with both sides of the sleeve, and the guide roller 111 also keeps the top of the outer side surface of the sleeve in contact. When pushing the tube, the rolling of the guide roller 111 drives the sleeve to move, and the balls 406 roll accordingly and smoothly move the sleeve out.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
