Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe crimping machines, and particularly relates to a pipe crimping machine with the function of preventing repeated pipe crimping. Background Art
[0002] In the production process of battery coolers for new energy vehicles, a tube pressing machine is required to press the coolant delivery pipe to the coolant outlet and coolant inlet of the battery cooler.
[0003] The existing technology requires the use of a pipe crimping machine to periodically press the pipe into the workpiece to be crimped (the workpiece that needs to be crimped). Since the existing technology removes the already crimped workpiece (the workpiece that has completed the crimping operation) manually or automatically, and the existing pipe crimping machine cannot detect whether the workpiece placed on the pipe crimping machine is pressed with pipes, if the already crimped workpiece is not removed in time due to external factors (such as the worker leaving the workstation or the already crimped workpiece being stuck), the pipe crimping machine will drive the pipe to move toward the workpiece already pressed with pipes. Therefore, the existing pipe crimping machine has a problem that the workpiece already pressed with pipes placed on the pipe crimping machine is repeatedly crimped due to the inability to detect whether the workpiece placed on the pipe crimping machine is pressed with pipes, thereby causing damage to the pipes and the workpieces.
[0004] Therefore, the existing technology needs to be improved and developed. Utility Model Content
[0005] The purpose of the present application is to provide a tube crimping machine with a function of preventing repeated tube crimping, which can effectively solve the problem that the workpiece placed on the tube crimping machine with tubes already pressed thereon is unable to detect whether there are tubes pressed thereon, resulting in repeated tube crimping of the workpiece, thereby causing damage to the tubes and the workpiece.
[0006] The present application provides a pipe crimping machine with a function of preventing repeated pipe crimping, comprising:
[0007] A frame on which the workpiece to be pressed is placed;
[0008] A fixture assembly, mounted on the frame;
[0009] A first driving assembly is installed on the frame and is used to drive the clamp assembly to clamp the pipe workpiece to be pressed on the frame;
[0010] The pipe pressing assembly is slidably mounted on the frame and is located on one side of the pipe workpiece to be pressed, and the pipe is placed at the upper limit thereof;
[0011] A second driving assembly is mounted on the frame and connected to the pipe pressing assembly, and is used to drive the pipe pressing assembly to move toward or away from the pipe workpiece to be pressed;
[0012] The first in-position detection component is installed on the frame and located at one side between the pipe workpiece to be pressed and the pipe pressing component, and is used to detect whether there is a pipe pressed on the pipe workpiece to be pressed.
[0013] The present application provides a tube pressing machine with a function of preventing repeated tube pressing, including a frame, a clamp assembly, a first drive assembly, a tube pressing assembly, a second drive assembly and a first in-place detection assembly. Since the first in-place detection assembly can detect whether there is a tube pressed on the workpiece to be pressed, and only when there is no tube pressed on the workpiece to be pressed, the second drive assembly will drive the tube pressing assembly to move toward the workpiece to be pressed, so as to press the tube placed at the upper limit of the tube pressing assembly into the workpiece to be pressed. Therefore, the present application is equivalent to providing a tube pressing machine that can detect whether there is a tube pressed on the workpiece placed on the frame and only press the tube into the workpiece without the tube pressed. That is, even if the workpiece with the tube pressed is not removed in time due to external factors, the tube pressing machine of the present application will not drive the tube to move toward the workpiece with the tube pressed, thereby effectively solving the problem that the workpiece with the tube pressed on the tube pressing machine is repeatedly pressed due to the inability to detect whether there is a tube pressed on the workpiece placed on the tube pressing machine, thereby causing damage to the tube and the workpiece.
[0014] Furthermore, the tube crimping machine with the function of preventing repeated tube crimping also includes multiple guide blocks, and the multiple guide blocks are arranged in a rectangular array on the frame. The guide blocks include a shrinking block and a limit block. The shrinking block is located above the limit block, and the shrinking block shrinks toward the limit block.
[0015] Since the shrinking block of the technical solution shrinks toward the limiting block, the shrinking block can guide the pipe workpiece to be pressed when the pipe workpiece to be pressed is placed on the rack, so that the pipe workpiece to be pressed can be smoothly placed on the rack. Since the limiting block can limit the placement position of the pipe workpiece to be pressed, the technical solution can effectively avoid the situation where the pipe placed on the pipe pressing assembly cannot be smoothly pressed into the pipe workpiece to be pressed due to the deviation between the actual placement position of the pipe workpiece to be pressed and the expected placement position.
[0016] Furthermore, the clamp assembly includes a clamping seat and a swing arm body, the clamping seat is fixed on the frame, the swing arm body is hinged to the clamping seat, and the output end of the first drive assembly and the pipe workpiece to be pressed are respectively located on both sides of the clamping seat.
[0017] Furthermore, the clamp assembly also includes a connecting rod, a connecting block, a first connecting rod, a second connecting rod and a third connecting rod. The connecting rod is fixed on the output end of the first driving assembly, the connecting block is fixed on the connecting rod, the two ends of the first connecting rod are respectively hinged to the connecting block and an end of the swing arm body away from the workpiece to be pressed, the two ends of the second connecting rod are respectively hinged to the connecting block and the middle part of the third connecting rod, and the two ends of the third connecting rod are respectively hinged to the clamping seat and the swing arm body.
[0018] Since the two ends of the first connecting rod are respectively hinged to the connecting block and the end of the swing arm body away from the pipe workpiece to be pressed, the two ends of the second connecting rod are respectively hinged to the connecting block and the middle part of the third connecting rod, and the two ends of the third connecting rod are respectively hinged to the clamping seat and the swing arm body. Therefore, when the first driving component drives the swing arm body to swing upward away from the end of the pipe workpiece to be pressed, the contact position between the output end of the first driving component and the connecting rod and the swing arm body will not change, thereby effectively solving the problem of wear between the output end of the first driving component and the swing arm body due to the continuous change of the contact position between the output end of the first driving component and the swing arm body.
[0019] Furthermore, the tube crimping machine with the function of preventing repeated tube crimping also includes a coding device, which is fixed on the frame and is used to code the tube-crimped workpiece.
[0020] Furthermore, a workpiece placement table is provided on the frame, and the workpiece placement table is used to place the workpiece to be pressed. The pipe pressing machine with the function of preventing repeated pipe pressing also includes a second in-place detection component and a third in-place detection component. The second in-place detection component and the third in-place detection component are symmetrically arranged on the frame with the center of the workpiece placement table as the symmetry center. The second in-place detection component and the third in-place detection component are used to detect whether the workpiece to be pressed is correctly placed on the workpiece placement table.
[0021] Since the second in-place detection component and the third in-place detection component are symmetrically arranged on the frame with the center of the workpiece placement table as the symmetrical center, the technical solution can detect whether the pipe workpiece to be pressed is correctly placed on the workpiece placement table through the second in-place detection component and the third in-place detection component, thereby further avoiding the situation where the pipe placed on the pipe pressing component cannot be smoothly pressed into the pipe workpiece to be pressed due to the deviation between the actual placement position of the workpiece to be pressed and the expected placement position.
[0022] Furthermore, a first slide rail is provided on the frame, a first slider is slidably installed on the first slide rail, the pipe pressing assembly includes a pressing head, the pressing head is installed on the first slider, a slot is provided on the side of the pressing head close to the second driving assembly, a connecting head is provided in the slot, the connecting head is connected to the output end of the second driving assembly, and a pipe is limitedly placed at one end of the pressing head away from the second driving assembly.
[0023] Furthermore, there are two pipe crimping assemblies, the connecting head is slidably installed in the card slot, the second drive assembly is slidably installed on the frame, and the pipe crimping machine with the function of preventing repeated pipe crimping also includes a third drive assembly, which is installed on the frame and connected to the second drive assembly. The third drive assembly is used to drive the second drive assembly to slide, and the driving direction of the third drive assembly is perpendicular to the driving direction of the second drive assembly.
[0024] This technical solution is equivalent to pressing two pipes into the pipe workpiece to be pressed in sequence. Since the second drive component of this technical solution only needs to drive one pipe pressing component to move toward or away from the pipe workpiece to be pressed at the same time, the output power of the second drive component of this technical solution is less than the output power of the second drive component when driving two pipe pressing components to move toward or away from the pipe workpiece to be pressed at the same time. Since the output power of the second drive component is positively correlated with its price, that is, this technical solution can select a relatively cheap second drive component. Therefore, this technical solution can effectively reduce the equipment cost of the pipe pressing machine under the premise of pressing two pipes into the pipe workpiece to be pressed at one time.
[0025] Furthermore, a second slide rail is provided on the frame, the second slide rail is located on the side of the pipe pressing assembly away from the pipe workpiece to be pressed, a second slider is slidably installed on the second slide rail, and the second drive assembly is installed on the second slider.
[0026] Furthermore, limit blocks are provided on both sides of the second slide rail.
[0027] Limit blocks are provided on both sides of the second slide rail of the technical solution, so the technical solution can limit the sliding position of the second drive component, thereby effectively avoiding the situation where the connector slides out of the slot due to excessive movement of the second drive component.
[0028] As can be seen from the above, the utility model provides a tube pressing machine with the function of preventing repeated tube pressing, including a frame, a clamp assembly, a first drive assembly, a tube pressing assembly, a second drive assembly and a first in-place detection assembly. Since the first in-place detection assembly can detect whether there is a tube pressed on the workpiece to be pressed, and only when there is no tube pressed on the workpiece to be pressed, the second drive assembly will drive the tube pressing assembly to move toward the workpiece to be pressed, so as to press the tube placed at the upper limit of the tube pressing assembly into the workpiece to be pressed. Therefore, the present application is equivalent to providing a tube pressing machine that can detect whether there is a tube pressed on the workpiece placed on the frame and only press the tube into the workpiece without the tube pressed. That is, even if the workpiece with the tube pressed is not removed in time due to external factors, the tube pressing machine of the present application will not drive the tube to move toward the workpiece with the tube pressed, thereby effectively solving the problem that the workpiece with the tube pressed on the tube pressing machine is repeatedly pressed due to the inability to detect whether there is a tube pressed on the workpiece placed on the tube pressing machine, thereby causing damage to the tube and the workpiece.

In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention.

[0038] like Figure 1-Figure 6As shown, the present application provides a pipe pressing machine with a function of preventing repeated pipe pressing, which includes:
[0039] A frame 1, on which a pipe workpiece 2 to be pressed is placed;
[0040] A fixture assembly 3 is mounted on the frame 1;
[0041] The first driving assembly 4 is installed on the frame 1 and is used to drive the clamp assembly 3 to clamp and fix the pipe workpiece 2 to be pressed on the frame 1;
[0042] The pipe pressing assembly 5 is slidably mounted on the frame 1 and is located on one side of the pipe workpiece 2 to be pressed, and a pipe 15 is placed at its upper limit;
[0043] A second driving assembly 6 is mounted on the frame 1 and is used to drive the pipe pressing assembly 5 to move toward or away from the pipe workpiece 2 to be pressed;
[0044] The first in-position detection component 24 is installed on the frame 1 and is located at one side between the pipe workpiece 2 to be pressed and the pipe pressing component 5, and is used to detect whether there is a pipe 15 pressed on the pipe workpiece 2 to be pressed.
[0045] Among them, a workpiece 2 to be pressed is placed on the rack 1 of this embodiment. The workpiece 2 to be pressed is a workpiece that needs to be pressed. The workpiece 2 to be pressed is preferably a battery cooler for a new energy vehicle. This embodiment can place the workpiece 2 to be pressed on the rack 1 manually or automatically (for example, using a robotic arm). The clamp assembly 3 of this embodiment is installed on the rack 1. The clamp assembly 3 can be a swing arm, a rocker, or a positioning fixture that can clamp the workpiece 2 to be pressed on the rack 1 under the driving action of an external power source. The first drive assembly 4 of this embodiment can be a cylinder or an oil cylinder that can drive the clamp assembly 3 to clamp the workpiece 2 to be pressed on the rack 1. The first drive assembly 4 is installed on the rack 1. The first drive assembly 4 of this embodiment is preferably a cylinder. The clamp assembly 3 and the first drive assembly 4 of this embodiment together constitute a rapid pneumatic clamp, that is, this embodiment is equivalent to using a rapid pneumatic clamp to quickly lock the workpiece 2 to be pressed. The tube pressing assembly 5 of this embodiment is slidably mounted on the frame 1 (i.e., the tube pressing assembly 5 can slide relative to the frame 1) and is located on one side of the tube workpiece 2 to be pressed. The tube pressing assembly 5 is placed with a tube 15 that needs to be pressed into the tube workpiece 2 to be pressed at the upper limit position. Specifically, the tube 15 is placed at the side of the tube pressing assembly 5 close to the tube workpiece 2 to be pressed. This embodiment can limit the placement position of the tube 15 by making the tube 15 away from the side of the tube workpiece 2 to be pressed and collide with the tube pressing assembly 5. The second drive assembly 6 of this embodiment is mounted on the frame 1 and connected to the tube pressing assembly 5. The second drive assembly 6 can be an electric cylinder, an air cylinder, or an oil cylinder that can drive the tube pressing assembly 5 to move toward or away from the tube workpiece 2 to be pressed. Since the electric cylinder has the advantages of high motion control accuracy, energy saving, and long service life, the second drive assembly 6 of this embodiment is preferably an electric cylinder. The first in-place detection component 24 of this embodiment can be a component such as a photoelectric switch or a photoelectric sensor that can detect whether a pipe 15 is pressed on the pipe workpiece 2 to be pressed. The first in-place detection component 24 is installed on the frame 1 and is located on one side between the pipe workpiece 2 to be pressed and the pipe pressing component 5. Specifically, the first in-place detection component 24 of this embodiment is a photoelectric sensor. The working principle of the first in-place detection component 24 of this embodiment to detect whether a pipe 15 is pressed on the pipe workpiece 2 to be pressed is: since the first in-place detection component 24 is located between the pipe workpiece 2 to be pressed and the pipe pressing component 5, if a pipe 15 is pressed on the pipe workpiece 2 to be pressed, the light emitted by the transmitter of the photoelectric sensor will be blocked by the pipe 15, that is, the receiver of the photoelectric sensor cannot receive the light emitted by the transmitter; if no pipe 15 is pressed on the pipe workpiece 2 to be pressed, the light emitted by the transmitter of the photoelectric sensor will not be blocked, that is, the receiver of the photoelectric sensor can receive the light emitted by the transmitter. Therefore, the first in-place detection component 24 of this embodiment can detect whether a pipe 15 is pressed on the pipe workpiece 2 to be pressed by judging whether the receiver receives the light emitted by the transmitter.
[0046] The present application provides a pipe pressing work flow of a pipe pressing machine with a function of preventing repeated pipe pressing, which can be as follows: A1. After placing the pipe workpiece 2 to be pressed on the frame 1, control the first drive component 4 to drive the clamp component 3 to clamp and fix the pipe workpiece 2 to be pressed on the frame 1; A2. Use the first in-place detection component 24 to detect whether there is a pipe 15 pressed on the pipe workpiece 2 to be pressed; A3. When it is detected that there is no pipe 15 pressed on the pipe workpiece 2 to be pressed, control the second drive component 6 to drive the pipe pressing component 5 to move toward the pipe workpiece 2 to be pressed, so as to press the pipe 15 placed at the upper limit of the pipe pressing component 5 into the pipe workpiece 2 to be pressed; A4. Control the second drive component 6 to drive the pipe pressing component 5 to move away from the pipe workpiece that has been pressed (the pipe workpiece 2 to be pressed that has completed the pipe pressing operation); A5. Control the first drive component 4 to drive the clamp component 3 to reset, so as to release the clamping and fixation of the pipe workpiece that has been pressed, and move the pipe workpiece that has been pressed out manually or automatically. It should be understood that if step A2 detects that a pipe 15 is pressed onto the pipe workpiece 2 to be pressed, this embodiment directly executes step A5.
[0047] The present application provides a pipe pressing machine with a function of preventing repeated pipe pressing, comprising a frame 1, a clamp assembly 3, a first drive assembly 4, a pipe pressing assembly 5, a second drive assembly 6 and a first in-place detection assembly 24. Since the first in-place detection assembly 24 can detect whether a pipe 15 is pressed on the pipe workpiece 2 to be pressed, and only when there is no pipe 15 pressed on the pipe workpiece 2 to be pressed, the second drive assembly 6 will drive the pipe pressing assembly 5 to move toward the pipe workpiece 2 to be pressed, so as to press the pipe 15 placed at the upper limit of the pipe pressing assembly 5 into the pipe workpiece 2 to be pressed, the present application is equivalent to providing a The tube crimping machine is capable of detecting whether a tube 15 is pressed on a workpiece placed on a frame 1 and only pressing the tube 15 into a workpiece that is not pressed with the tube 15. That is, even if the workpiece that is pressed with the tube 15 is not removed in time due to external factors, the tube crimping machine of the present application will not drive the tube 15 to move toward the workpiece that is pressed with the tube 15. This effectively solves the problem that the workpiece that is pressed with the tube 15 is repeatedly pressed due to the inability to detect whether the workpiece placed on the tube crimping machine is pressed with the tube 15, thereby causing damage to the tube 15 and the workpiece.
[0048] In some embodiments, the tube crimping machine with the function of preventing repeated tube crimping also includes multiple guide blocks 7, and the multiple guide blocks 7 are arranged in a rectangular array on the frame 1. The guide blocks 7 include a retraction block 71 and a limit block 72. The retraction block 71 is located above the limit block 72, and the retraction block 71 retracts toward the limit block 72. The frame 1 of this embodiment has a plurality of guide blocks 7 in a rectangular array, and each guide block 7 includes a retraction block 71 and a limit block 72. The retraction block 71 is located above the limit block 72, and the retraction block 71 retracts toward the limit block 72. The limit block 72 can limit the placement position of the pipe workpiece 2 to be pressed. Since the retraction block 71 of this embodiment retracts toward the limit block 72, when the pipe workpiece 2 to be pressed is placed on the frame 1, the retraction block 71 can guide the pipe workpiece 2 to be pressed, so that the pipe workpiece 2 to be pressed can be smoothly placed on the frame 1. Since the limit block 72 can limit the placement position of the pipe workpiece 2 to be pressed, this embodiment can effectively avoid the situation where the pipe 15 placed on the pipe pressing assembly 5 cannot be smoothly pressed into the pipe workpiece 2 to be pressed due to the deviation between the actual placement position of the pipe workpiece 2 to be pressed and the expected placement position.
[0049] In some embodiments, the clamp assembly 3 includes a clamping seat 31 and a swing arm body 32. The clamping seat 31 is fixed on the frame 1. The swing arm body 32 is hinged to the clamping seat 31. The output end of the first drive assembly 4 and the pipe workpiece 2 to be pressed are respectively located on both sides of the clamping seat 31. The clamping seat 31 of this embodiment can be fixed to the frame 1 by welding or screw locking, and the swing arm body 32 is hinged to the clamping seat 31, that is, the swing arm body 32 can swing relative to the clamping seat 31. This embodiment controls the first drive assembly 4 to drive the swing arm body 32 to swing upward away from one end of the pipe workpiece 2 to be pressed, so as to clamp and fix the pipe workpiece 2 to be pressed on the frame 1. It should be understood that a push rod is provided on the swing arm body 32 of this embodiment to cooperate with the swing arm body 32 to clamp the edge of the pipe workpiece 2 to be pressed.
[0050] When the first driving component 4 drives the swing arm body 32 to swing upward away from one end of the pipe workpiece 2 to be pressed, the contact position between the output end of the first driving component 4 of the above embodiment and the swing arm body 32 will continuously change, that is, the output end of the first driving component 4 will continuously rub against the swing arm body 32, thereby causing wear between the output end of the first driving component 4 and the swing arm body 32.
[0051] In order to solve this technical problem, in some embodiments, the clamp assembly 3 also includes a connecting rod 33, a connecting block 34, a first connecting rod 35, a second connecting rod 36 and a third connecting rod 37. The connecting rod 33 is fixed on the output end of the first driving assembly 4, the connecting block 34 is fixed on the connecting rod 33, and the two ends of the first connecting rod 35 are respectively hinged to the connecting block 34 and the end of the swing arm body 32 away from the pipe workpiece 2 to be pressed, the two ends of the second connecting rod 36 are respectively hinged to the connecting block 34 and the middle part of the third connecting rod 37, and the two ends of the third connecting rod 37 are respectively hinged to the clamping seat 31 and the swing arm body 32. Since the two ends of the first connecting rod 35 are respectively hinged to the connecting block 34 and the end of the swing arm body 32 away from the pipe workpiece 2 to be pressed, the two ends of the second connecting rod 36 are respectively hinged to the connecting block 34 and the middle part 37 of the third connecting rod, and the two ends of the third connecting rod 37 are respectively hinged to the clamping seat 31 and the swing arm body 32. Therefore, when the first driving component 4 drives the swing arm body 32 to swing upward away from the end of the pipe workpiece 2 to be pressed, the contact position between the output end of the first driving component 4 and the connecting rod 33 and the swing arm body 32 will not change, thereby effectively solving the problem of wear between the output end of the first driving component 4 and the swing arm body 32 due to the continuous change of the contact position between the output end of the first driving component 4 and the swing arm body 32.
[0052] In some embodiments, the tube crimping machine with the function of preventing repeated tube crimping further includes a coder 8, which is fixed on the frame 1 and is used to code the pressed tube workpiece. The coder 8 of this embodiment can be an existing coder or inkjet printer, which is fixed on the frame 1. This embodiment identifies the pressed tube workpiece by using the coder 8 to code the pressed tube workpiece.
[0053] In some embodiments, a workpiece placement table 9 is provided on the frame 1, and the workpiece placement table 9 is used to place the workpiece 2 to be pressed. The pipe pressing machine with the function of preventing repeated pipe pressing also includes a second in-place detection component 10 and a third in-place detection component 11. The second in-place detection component 10 and the third in-place detection component 11 are symmetrically arranged on the frame 1 with the center of the workpiece placement table 9 as the center of symmetry. The second in-place detection component 10 and the third in-place detection component 11 are used to detect whether the workpiece 2 to be pressed is correctly placed on the workpiece placement table 9. Specifically, the rectangular array of the workpiece placement table 9 of this embodiment has multiple placement columns, and the workpiece 2 to be pressed is placed on the placement columns. The second in-place detection component 10 and the third in-place detection component 11 of this embodiment can be components such as photoelectric sensors or photoelectric switches. Since the second in-place detection component 10 and the third in-place detection component 11 are symmetrically arranged on the frame 1 with the center of the workpiece placement table 9 as the symmetry center, this embodiment can detect whether the workpiece 2 to be pressed is correctly placed on the workpiece placement table 9 through the second in-place detection component 10 and the third in-place detection component 11 (for example, by judging whether the receivers of the second in-place detection component 10 and the third in-place detection component 11 both receive the light emitted by the transmitter to detect whether the workpiece 2 to be pressed is correctly placed on the workpiece placement table 9), thereby further avoiding the situation where the pipe 15 placed on the pipe pressing component 5 cannot be smoothly pressed into the workpiece 2 to be pressed due to the deviation between the actual placement position of the workpiece 2 to be pressed and the expected placement position. It should be understood that this embodiment will press the pipe 15 placed at the upper limit of the pipe pressing assembly 5 into the pipe workpiece 2 only when it is detected that the pipe workpiece 2 to be pressed is correctly placed on the workpiece placement table 9 and there is no pipe 15 pressed on the pipe workpiece 2 to be pressed.
[0054] In some embodiments, a first slide rail 12 is provided on the frame 1, a first slider 13 is slidably mounted on the first slide rail 12, and the tube pressing assembly 5 includes a pressure head 51, the pressure head 51 is mounted on the first slider 13, a slot 52 is provided on the side of the pressure head 51 close to the second drive assembly 6, a connector 14 is provided in the slot 52, the connector 14 is connected to the output end of the second drive assembly 6, and a pipe 15 is placed at one end of the pressure head 51 away from the second drive assembly 6. The first slide rail 12 of this embodiment is fixed on the frame 1, a slot 52 is provided on the side of the pressure head 51 close to the second drive assembly 6, a connector 14 is provided in the slot 52, and the cross-sectional area of the connector 14 is larger than the opening area at the top of the slot 52, that is, the slot 52 can prevent the connector 14 from moving relative to the pressure head 51 along the driving direction of the second drive assembly 6.
[0055] In some embodiments, the number of the tube pressing assemblies 5 is two, and the two pressing heads 51 are fixedly connected. The number of the first slide rails 12 of this embodiment is two, and a first slider 13 is slidably mounted on each first slide rail 12. The two pressing heads 51 are respectively mounted on the first sliders 13 of different first slide rails 12, and the card slots 52 of the two pressing heads 51 are interconnected. Since the number of the tube pressing assemblies 5 of this embodiment is two, and the two pressing heads 51 are fixedly connected, that is, the two pressing heads 51 cannot slide relative to each other, the second drive assembly 6 of this embodiment can simultaneously drive the two tube pressing assemblies 5 to move toward or away from the workpiece 2 to be pressed, that is, this embodiment can press two pipes 15 into the workpiece 2 to be pressed at one time, thereby effectively improving the tube pressing efficiency of the tube pressing machine. It should be understood that since the second drive assembly 6 of this embodiment needs to press two pipes 15 into the workpiece 2 to be pressed at the same time, the second drive assembly 6 of this embodiment needs to have a sufficiently large output power.
[0056] In some embodiments, the number of the tube pressing assemblies 5 is two, the connector 14 is slidably mounted in the card slot 52, the second drive assembly 6 is slidably mounted on the frame 1, and the tube pressing machine with the function of preventing repeated tube pressing also includes a third drive assembly 16, the third drive assembly 16 is mounted on the frame 1 and connected to the second drive assembly 6, the third drive assembly 16 is used to drive the second drive assembly 6 to slide, and the driving direction of the third drive assembly 16 is perpendicular to the driving direction of the second drive assembly 6. The number of the tube pressing assemblies 5 of this embodiment is two, the connector 14 is slidably mounted in the card slot 52, that is, the connector 14 can slide relative to the card slot 52, the second drive assembly 6 of this embodiment is slidably mounted on the frame 1, that is, the second drive assembly 6 can slide relative to the frame 1, and the third drive assembly 16 of this embodiment can be an electric cylinder, a gas cylinder, or an oil cylinder, etc., which can drive the second drive assembly 6 to slide. Since there is no connection between the two pressing tube components 5 of this embodiment, the two pressing tube components 5 of this embodiment can slide relative to each other. The specific process of pressing the pipe 15 into the pipe workpiece 2 to be pressed in this embodiment can be: B1, control the third driving component 16 to drive the second driving component 6 to slide, so as to move the connecting head 14 into the slot 52 of one of the pressing heads 51; B2, control the second driving component 6 to drive the pressing head 51 corresponding to the slot 52 where the connecting head 14 is located to move toward the pipe workpiece 2 to be pressed, so as to move the pressing head 51 upward. The limited-positioned pipe 15 is pressed into the pipe workpiece 2 to be pressed; B3, control the second drive component 6 to drive the pressure head 51 corresponding to the slot 52 where the connecting head 14 is located to move away from the pipe workpiece 2 to be pressed, until the slots 52 of the two pressure heads 51 are connected to each other; B4, control the third drive component 16 to drive the second drive component 6 to slide, so as to move the connecting head 14 to the slot 52 of the other pressure head 51; B5, execute steps B2 and B3 to press the pipe 15 limited-positioned by the other pressure head 51 into the pipe workpiece 2 to be pressed. This embodiment is equivalent to pressing two pipes 15 into the pipe workpiece 2 to be pressed in sequence. Since the second drive component 6 of this embodiment only needs to drive one pipe pressing component 5 to move toward or away from the pipe workpiece 2 to be pressed at the same time, the output power of the second drive component 6 of this embodiment is less than the output power of the second drive component 6 when driving two pipe pressing components 5 to move toward or away from the pipe workpiece 2 to be pressed at the same time. Since the output power of the second drive component 6 is positively correlated with its price, that is, this embodiment can use a relatively cheap second drive component 6, so this embodiment can effectively reduce the equipment cost of the pipe pressing machine under the premise of pressing two pipes 15 into the pipe workpiece 2 to be pressed at one time. It should also be understood that this embodiment will only execute the above steps B1-B5 once when the first in-place detection component 24 detects that there is no pipe 15 pressed on the pipe workpiece 2 to be pressed.
[0057] In some embodiments, a positioning hole 19 is provided on the side wall of the pressing head 51, and the tube pressing machine with the function of preventing repeated tube pressing further comprises a first cylinder 22, a second cylinder 23 and two positioning heads, both of which are mounted on the frame 1, and the two positioning heads are respectively fixedly connected to the piston ends of the first cylinder 22 and the second cylinder 23, and both of the first cylinder 22 and the second cylinder 23 are used to insert the positioning heads into the positioning holes 19. When the positioning heads are inserted into the positioning holes 19, the position of the pressing head 51 corresponding to the positioning holes 19 is locked. By default, both the first cylinder 22 and the second cylinder 23 insert the positioning head into the positioning hole 19. When the connecting head 14 moves to the slot 52 of the pressure head 51 near the first cylinder 22, the first cylinder 22 drives the positioning head to move away from the pressure head 51, so that the second drive assembly 6 can drive the pressure head 51 to move toward or away from the pipe workpiece 2 to be pressed. After the pipe 15 placed at the upper limit position near the pressure head 51 of the first cylinder 22 is pressed into the pipe workpiece 2 to be pressed, the first cylinder 22 controls the positioning head to move toward the pressure head 51 to insert the positioning head into the positioning hole 19. This embodiment is equivalent to avoiding the situation in which the connecting head 14 cannot be moved to the slot 52 of the pressure head 51 corresponding to the other pipe 15 due to the displacement of the pressure head 51 corresponding to the other pipe 15 when one of the pipes 15 is pressed into the pipe workpiece 2 to be pressed.
[0058] In some embodiments, the frame 1 is further provided with a second slide rail 17, the second slide rail 17 is located on the side of the pipe pressing assembly 5 away from the pipe workpiece 2 to be pressed, a second slider 18 is slidably mounted on the second slide rail 17, and the second drive assembly 6 is mounted on the second slider 18. The second slide rail 17 of this embodiment is fixed on the frame 1, the second slide rail 17 is located on the side of the pipe pressing assembly 5 away from the pipe workpiece 2 to be pressed, and a plurality of second sliders 18 are slidably mounted on the second slide rail 17 of this embodiment. Preferably, two second slide rails 17 are provided on the frame 1 of this embodiment, and two second sliders 18 are slidably mounted on each second slide rail 17, and this embodiment can effectively improve the stability of driving the second drive assembly 6 to move. Since the driving direction of the third drive assembly 16 is perpendicular to the driving direction of the second drive assembly 6, the extension direction of the first slide rail 12 of this embodiment is perpendicular to the extension direction of the second slide rail 17.
[0059] In some embodiments, both sides of the second slide rail 17 are provided with limit blocks 72. In this embodiment, both sides of the second slide rail 17 are provided with limit blocks 72, so this embodiment can limit the sliding position of the second drive assembly 6, thereby effectively avoiding the situation where the connector 14 slides out of the slot 52 due to excessive movement of the second drive assembly 6. Preferably, the limit blocks 72 of this embodiment are provided with hydraulic buffers 20 and polyurethane stoppers 21, and the hydraulic buffers 20 and polyurethane stoppers 21 can both play a role in preventing the second drive assembly 6 from directly contacting the limit blocks 72, so this embodiment can effectively avoid the situation where the second drive assembly 6 and the limit blocks 72 are damaged or even destroyed due to direct contact between the second drive assembly 6 and the limit blocks 72.
[0060] As can be seen from the above, the utility model provides a tube pressing machine with a function of preventing repeated tube pressing, including a frame 1, a clamp assembly 3, a first drive assembly 4, a tube pressing assembly 5, a second drive assembly 6 and a first in-place detection assembly 24. Since the first in-place detection assembly 24 can detect whether a tube 15 is pressed on the tube workpiece 2 to be pressed, and only when there is no tube 15 pressed on the tube workpiece 2 to be pressed, the second drive assembly 6 will drive the tube pressing assembly 5 to move toward the tube workpiece 2 to be pressed, so as to press the tube 15 placed at the upper limit of the tube pressing assembly 5 into the tube workpiece 2 to be pressed, so the present application is equivalent to providing A tube pressing machine is disclosed which is capable of detecting whether a tube 15 is pressed onto a workpiece placed on a frame 1 and only pressing the tube 15 into a workpiece onto which no tube 15 is pressed. That is, even if the workpiece onto which the tube 15 is pressed is not removed in time due to external factors, the tube pressing machine of the present application will not drive the tube 15 to move toward the workpiece onto which the tube 15 is pressed, thereby effectively solving the problem that the workpiece onto which the tube 15 is pressed is repeatedly pressed due to the inability to detect whether the workpiece placed on the tube pressing machine is pressed, thereby causing damage to the tube 15 and the workpiece.
