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 a function of preventing workpieces from shifting. 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 prior art requires the use of a pipe pressing machine to press the pipe into a workpiece to be pressed (a workpiece that needs to be pressed). The prior pipe pressing machine uses a clamping assembly to clamp the workpiece to be pressed on the frame in the vertical direction. Since the prior pipe pressing machine presses the pipe into the workpiece to be pressed in the horizontal direction, that is, the workpiece to be pressed will be subjected to a horizontal force during the pipe pressing process, and the clamping assembly only provides a vertical force to the workpiece to be pressed. Therefore, when the pipe is pressed into the workpiece to be pressed, the vertical force provided by the clamping assembly may be insufficient, and the friction force generated when the pipe is pressed may cause the workpiece to be pressed to slide in the pressing direction of the pipe (that is, the workpiece to be pressed is displaced in the pressing direction of the pipe). That is, the prior pipe pressing machine has the problem of failure to press the pipe into place or failure to press the pipe due to the displacement of the workpiece to be pressed in the pressing direction of the pipe during the pipe pressing process.

[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 pipe pressing machine with a function of preventing workpiece displacement, which can effectively solve the problem that the pipe cannot be pressed into or completely pressed into the workpiece to be pressed due to displacement of the workpiece to be pressed during the pipe pressing process.

[0006] The present application provides a pipe crimping machine with a function of preventing workpiece displacement, comprising:

[0007] A frame on which the workpiece to be pressed is placed;

[0008] A clamping assembly is installed on the frame and is used to clamp and fix the pipe workpiece to be pressed on the frame in the vertical direction;

[0009] 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 on the upper limit thereof;

[0010] A first 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;

[0011] A tightening assembly is slidably mounted on the frame and is located on the other side of the pipe workpiece to be pressed;

[0012] The second driving assembly is installed on the frame and connected to the pressing assembly, and is used to drive the pressing assembly to move toward or away from the pipe workpiece to be pressed.

[0013] The present application provides a pipe pressing machine with a function of preventing workpiece displacement, including a frame, a clamping assembly, a pipe pressing assembly, a first drive assembly, a clamping assembly and a second drive assembly. Since the pipe pressing assembly and the first drive assembly as well as the clamping assembly and the second drive assembly are respectively arranged on both sides of the pipe workpiece to be pressed, during the pipe pressing process, the clamping assembly can limit the position of the pipe workpiece to be pressed away from one end of the first drive assembly to ensure that the pipe workpiece to be pressed does not move along the pressing direction of the pipe. Therefore, when the pipe is pressed into the workpiece to be pressed, even if the vertical force provided by the clamping assembly is insufficient, the present application will not cause the workpiece to be pressed to shift along the pressing direction of the pipe, that is, the present application can completely press the pipe into the workpiece to be pressed, that is, the present application can effectively solve the problem of inadequate or failed pressing of the pipe due to the displacement of the workpiece to be pressed along the pressing direction of the pipe during the pipe pressing process.

[0014] 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 first driving assembly, a connecting head is provided in the slot, the connecting head is connected to the output end of the first driving assembly, and a pipe is limitedly placed at one end of the pressing head away from the first driving assembly.

[0015] Furthermore, there are two pipe crimping assemblies, the connecting head is slidably installed in the card slot, the first drive assembly is slidably installed on the frame, and the pipe crimping machine with the function of preventing the workpiece from shifting also includes a third drive assembly, which is installed on the frame and connected to the first drive assembly. The third drive assembly is used to drive the first drive assembly to slide, and the driving direction of the third drive assembly is perpendicular to the driving direction of the first drive assembly.

[0016] This technical solution is equivalent to pressing two pipes into the pipe workpiece to be pressed in sequence. Since the first 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, the output power of the first drive component of this technical solution is less than the output power of the first drive component when simultaneously driving two pipe pressing components to move toward or away from the pipe workpiece to be pressed. Since the output power of the first drive component is positively correlated with its price, that is, this technical solution can select a relatively cheap first 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.

[0017] 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 first drive assembly is installed on the second slider.

[0018] Furthermore, limit blocks are provided on both sides of the second slide rail.

[0019] 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 first drive component, thereby effectively avoiding the situation where the connector slides out of the slot due to excessive movement of the first drive component.

[0020] Furthermore, a sensing bracket is fixed on one side of the first driving component close to the pressing tube component, and a first in-place detection component and a second in-place detection component are provided between the first driving component and the pressing head.

[0021] Furthermore, the tightening assembly includes a floating cylinder base, which is slidably mounted on the frame, and a plurality of floating support cylinders are mounted on one side of the floating cylinder base close to the pipe workpiece to be pressed, and the second driving assembly is connected to the floating cylinder base.

[0022] Furthermore, the number of the floating support cylinders is two, and the two floating support cylinders are symmetrically installed on the floating support cylinder base with the center of the floating support cylinder base as the symmetry center.

[0023] Since the number of floating support cylinders in this technical solution is two, that is, the clamping assembly of this technical solution is equivalent to simultaneously contacting two positions of the pipe workpiece to be pressed, so that the force on the pipe workpiece to be pressed is more uniform, this technical solution can effectively improve the clamping effect of the clamping assembly.

[0024] Furthermore, the pipe crimping machine with the function of preventing the workpiece from shifting also includes a second limit assembly, which is installed on the frame and is used to lock the position of the floating cylinder base.

[0025] The second limiting component of the technical solution can be a component such as a limiting block or a limiting rod that can lock the position of the floating cylinder base. Since the second limiting component of the technical solution can prevent the clamping component from moving in a direction away from the pipe workpiece to be pressed, the technical solution can effectively avoid the situation where the clamping component and the second driving component cannot limit the position of the pipe workpiece to be pressed away from one end of the first driving component due to the excessive force provided to the pipe workpiece to be pressed by the first driving component and the pipe pressing component, resulting in the displacement of the pipe workpiece to be pressed in the pressing direction of the pipe. That is, the technical solution can further improve the clamping effect of the clamping component.

[0026] Furthermore, second positioning holes are provided on both sides of the floating cylinder base, and the second limiting assembly includes a third cylinder and a fourth cylinder, which are respectively installed on both sides of the floating cylinder base, and second positioning heads are fixed to the piston ends of the third cylinder and the fourth cylinder, and the third cylinder and the fourth cylinder can both insert the second positioning heads into the second positioning holes.

[0027] As can be seen from the above, the utility model provides a pipe pressing machine with the function of preventing workpiece displacement, including a frame, a clamping assembly, a pipe pressing assembly, a first drive assembly, a clamping assembly and a second drive assembly. Since the pipe pressing assembly and the first drive assembly as well as the clamping assembly and the second drive assembly are respectively arranged on both sides of the pipe workpiece to be pressed, during the pipe pressing process, the clamping assembly can limit the position of the pipe workpiece to be pressed away from one end of the first drive assembly to ensure that the pipe workpiece to be pressed does not move along the pressing direction of the pipe. Therefore, when the pipe is pressed into the workpiece to be pressed, even if the vertical force provided by the clamping assembly is insufficient, the present application will not cause the workpiece to be pressed to shift along the pressing direction of the pipe, that is, the present application can completely press the pipe into the workpiece to be pressed, that is, the present application can effectively solve the problem of inadequate or failed pressing of the pipe due to the displacement of the workpiece to be pressed along the pressing direction of the pipe during the pipe pressing process.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. 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. In addition, the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0037] like Figure 1-Figure 6 As shown, the present application provides a pipe pressing machine with a function of preventing workpiece displacement, which includes:

[0038] A frame 1 on which a pipe workpiece 2 to be pressed is placed;

[0039] The clamping assembly 3 is mounted on the frame 1 and is used to clamp and fix the pipe workpiece 2 to be pressed on the frame 1 in the vertical direction;

[0040] The pipe pressing assembly 4 is slidably mounted on the frame 1 and is located on one side of the pipe workpiece 2 to be pressed, and a pipe 21 is placed at its upper limit;

[0041] A first driving assembly 5 is mounted on the frame 1 and connected to the pipe pressing assembly 4, and is used to drive the pipe pressing assembly 4 to move toward or away from the pipe workpiece 2 to be pressed;

[0042] A clamping assembly 6 is slidably mounted on the frame 1 and is located on the other side of the pipe workpiece 2 to be pressed;

[0043] The second driving assembly 7 is installed on the frame 1 and connected to the pressing assembly 6, and is used to drive the pressing assembly 6 to move toward or away from the pipe workpiece 2 to be pressed.

[0044] 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 clamping assembly 3 of this embodiment is installed on the rack 1. The clamping assembly 3 can be a pneumatic clamp, an electric clamp, or a clamping block that can clamp the workpiece 2 to be pressed on the rack 1 in a vertical direction, that is, the clamping assembly 3 of this embodiment can provide a vertical downward force for the workpiece 2 to be pressed. The tube pressing assembly 4 of this embodiment is slidably mounted on the frame 1 (i.e., the tube pressing assembly 4 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 4 is placed with a tube 21 that needs to be pressed into the tube workpiece 2 to be pressed at an upper limit position. Specifically, the tube 21 is limitedly placed on the side of the tube pressing assembly 4 close to the tube workpiece 2 to be pressed. This embodiment can limit the placement position of the tube 21 by making the tube 21 away from the side of the tube workpiece 2 to be pressed collide with the tube pressing assembly 4. The sliding direction of the tube pressing assembly 4 is parallel to the axial direction of the tube 21. The first drive assembly 5 of this embodiment is mounted on the frame 1 and connected to the tube pressing assembly 4. The first drive assembly 5 can be an electric cylinder, an air cylinder, or an oil cylinder that can drive the tube pressing assembly 4 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 first drive assembly 5 of this embodiment is preferably an electric cylinder. The clamping assembly 6 of this embodiment is slidably mounted on the frame 1 (i.e., the clamping assembly 6 can slide relative to the frame 1) and is located on the other side of the pipe workpiece 2 to be pressed. The clamping assembly 6 of this embodiment can be a component such as a push block that can contact the side of the pipe workpiece 2 to be pressed away from the pipe pressing assembly 4. The second driving assembly 7 of this embodiment is mounted on the frame 1 and connected to the clamping assembly 6. The second driving assembly 7 can be a cylinder, an oil cylinder, or an electric cylinder that can drive the clamping assembly 6 to move toward or away from the pipe workpiece 2 to be pressed.

[0045] The pipe pressing workflow of a pipe pressing machine with a function of preventing workpiece displacement provided by the present application can be: A1. After placing the pipe workpiece 2 to be pressed on the frame 1, control the clamping assembly 3 to clamp and fix the pipe workpiece 2 to be pressed on the frame 1 in the vertical direction; A2. Control the second driving assembly 7 to drive the clamping assembly 6 to move toward the pipe workpiece 2 to be pressed, so that the clamping assembly 6 and the side of the pipe workpiece 2 to be pressed away from the pipe pressing assembly 4 are in conflict; A3. Control the first driving assembly 5 to drive the pipe pressing assembly 4 to move toward the pipe workpiece 2 to be pressed, so as to press the pipe 21 placed on the pipe pressing assembly 4 into the pipe workpiece 2 to be pressed; A4. Control the first driving assembly 5 to drive the pipe pressing assembly 4 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), and control the second driving assembly 7 to drive the clamping assembly 6 to move away from the pipe workpiece that has been pressed; A5. Control the clamping assembly 3 to release the clamping 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 since the pipe pressing assembly 4 and the first drive assembly 5 as well as the clamping assembly 6 and the second drive assembly 7 are respectively arranged on both sides of the pipe workpiece 2 to be pressed, during the pipe pressing process, the clamping assembly 6 can limit the position of the pipe workpiece 2 to be pressed away from one end of the first drive assembly 5 to ensure that the pipe workpiece 2 to be pressed does not move along the pressing direction of the pipe 21. Therefore, when the pipe 21 is pressed into the pipe workpiece 2 to be pressed, the present application will not cause the pipe workpiece 2 to be pressed to shift.

[0046] The present application provides a pipe pressing machine with a function of preventing workpiece displacement, including a frame 1, a clamping assembly 3, a pipe pressing assembly 4, a first drive assembly 5, a clamping assembly 6, and a second drive assembly 7. Since the pipe pressing assembly 4 and the first drive assembly 5 as well as the clamping assembly 6 and the second drive assembly 7 are respectively arranged on both sides of the pipe workpiece 2 to be pressed, during the pipe pressing process, the clamping assembly 6 can limit the position of the pipe workpiece 2 to be pressed away from one end of the first drive assembly 5 to ensure that the pipe workpiece 2 to be pressed does not move along the pressing direction of the pipe 21. Therefore, when the pipe 21 is pressed into the pipe workpiece 2 to be pressed, even if the vertical force provided by the clamping assembly 3 is insufficient, the present application will not cause the pipe workpiece 2 to be pressed to shift along the pressing direction of the pipe 21, that is, the present application can completely press the pipe 21 into the pipe workpiece 2 to be pressed, that is, the present application can effectively solve the problem of the pipe 21 not being pressed into place or the pipe 21 failing to be pressed due to the displacement of the pipe workpiece 2 to be pressed along the pressing direction of the pipe during the pipe pressing process.

[0047] In some embodiments, a first slide rail 19 is provided on the frame 1, a first slider 20 is slidably mounted on the first slide rail 19, and the tube pressing assembly 4 includes a pressure head 41, the pressure head 41 is mounted on the first slider 20, a slot 42 is provided on the side of the pressure head 41 close to the first drive assembly 5, a connector 17 is provided in the slot 42, the connector 17 is connected to the output end of the first drive assembly 5, and a pipe 21 is placed at one end of the pressure head 41 away from the first drive assembly 5. The first slide rail 19 of this embodiment is fixed on the frame 1, a slot 42 is provided on the side of the pressure head 41 close to the first drive assembly 5, a connector 17 is provided in the slot 42, and the cross-sectional area of ​​the connector 17 is larger than the opening area at the top of the slot 42, that is, the slot 42 can prevent the connector 17 from moving relative to the pressure head 41 along the driving direction of the first drive assembly 5.

[0048] In some embodiments, the number of the tube pressing assemblies 4 is two, and the two pressing heads 41 are fixedly connected. The number of the first slide rails 19 of this embodiment is two, and the first slider 20 is slidably mounted on each first slide rail 19. The two pressing heads 41 are respectively mounted on the first sliders 20 of different first slide rails 19, and the card slots 42 of the two pressing heads 41 are interconnected. Since the number of the tube pressing assemblies 4 of this embodiment is two, and the two pressing heads 41 are fixedly connected, that is, the two pressing heads 41 cannot slide relative to each other, the first drive assembly 5 of this embodiment can simultaneously drive the two tube pressing assemblies 4 to move toward or away from the workpiece 2 to be pressed, that is, this embodiment can press two pipes 21 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 first drive assembly 5 of this embodiment needs to press two pipes 21 into the workpiece 2 to be pressed at the same time, the first drive assembly 5 of this embodiment needs to have a sufficiently large output power.

[0049] In some embodiments, the number of the tube pressing assemblies 4 is two, the connector 17 is slidably installed in the card slot 42, the first drive assembly 5 is slidably installed on the frame 1, and the tube pressing machine with the function of preventing the workpiece from shifting further includes a third drive assembly 8, which is installed on the frame 1 and connected to the first drive assembly 5. The third drive assembly 8 is used to drive the first drive assembly 5 to slide, and the driving direction of the third drive assembly 8 is perpendicular to the driving direction of the first drive assembly 5. The number of the tube pressing assemblies 4 in this embodiment is two, the connector 17 is slidably connected to the card slot 42, that is, the connector 17 can slide relative to the card slot 42, the first drive assembly 5 in this embodiment is slidably installed on the frame 1, that is, the first drive assembly 5 can slide relative to the frame 1, and the third drive assembly 8 in this embodiment can be an electric cylinder, a pneumatic cylinder, or an oil cylinder, etc., which can drive the first drive assembly 5 to slide. Since there is no connection between the two pressing tube components 4 of this embodiment, the two pressing tube components 4 of this embodiment can slide relative to each other. The specific process of pressing the tube 21 into the workpiece 2 to be pressed can be as follows: B1, control the third driving component 8 to drive the first driving component 5 to slide, so as to move the connector 17 into the slot 42 of one of the pressing heads 41; B2, control the first driving component 5 to drive the pressing head 41 corresponding to the slot 42 where the connecting head 17 is located to move toward the workpiece 2 to be pressed, so as to move the pressing head 41 upward. The limited-positioned pipe 21 is pressed into the pipe workpiece 2 to be pressed; B3, control the first drive component 5 to drive the pressure head 41 corresponding to the slot 42 where the connecting head 17 is located to move away from the pipe workpiece 2 to be pressed, until the slots 42 of the two pressure heads 41 are connected to each other; B4, control the third drive component 8 to drive the first drive component 5 to slide, so as to move the connecting head 17 to the slot 42 of the other pressure head 41; B5, execute steps B2 and B3 to press the pipe 21 limited-positioned by the other pressure head 41 into the pipe workpiece 2 to be pressed. This embodiment is equivalent to pressing two pipes 21 into the pipe workpiece 2 to be pressed in sequence. Since the first drive component 5 of this embodiment only needs to drive one pipe pressing component 4 to move toward or away from the pipe workpiece 2 to be pressed, the output power of the first drive component 5 of this embodiment is less than the output power of the first drive component 5 when the two pipe pressing components 4 are simultaneously driven to move toward or away from the pipe workpiece 2 to be pressed. Since the output power of the first drive component 5 is positively correlated with its price, that is, this embodiment can select a relatively cheap first drive component 5. Therefore, this embodiment can effectively reduce the equipment cost of the pipe pressing machine under the premise of pressing two pipes 21 into the pipe workpiece 2 to be pressed at one time.

[0050] In some embodiments, the pipe crimping machine with the function of preventing the workpiece from shifting further includes a first limit assembly 18, which is mounted on the frame 1, and is used to lock the position of the pressing head 41. The first limit assembly 18 of this embodiment may be a component such as a limit rod or a limit head that can be inserted into the first positioning hole 22 to lock the position of the pressing head 41. Preferably, the number of pressing heads 41 is two, and the first limit assembly 18 includes a first cylinder 1801 and a second cylinder 1802, and the first cylinder 1801 and the second cylinder 1802 are both fixed with a first positioning head, and the first cylinder 1801 and the second cylinder 1802 are both able to insert the first positioning head into the first positioning hole 22. Specifically, by default, the first cylinder 1801 and the second cylinder 1802 both insert the first positioning head into the first positioning hole 22, and when the connecting head 17 moves to the slot 42 of the pressing head 41 close to the first cylinder 1801, the first cylinder 1 801 drives the first positioning head to move away from the pressure head 41, so that the first driving component 5 can drive the pressure head 41 to move toward or away from the pipe workpiece 2 to be pressed. After the pipe 21 placed at the upper limit of the pressure head 41 near the first cylinder 1801 is pressed into the pipe workpiece 2 to be pressed, the first cylinder 1801 controls the first positioning head to move toward the pressure head 41 to insert the first positioning head into the first positioning hole 22. This embodiment is equivalent to setting the first limit component 18 to avoid the situation in which the connecting head 17 cannot be moved to the slot 42 of the pressure head 41 corresponding to the other pipe 21 due to the displacement of the pressure head 41 corresponding to the other pipe 21 when one of the pipes 21 is pressed into the pipe workpiece 2 to be pressed.

[0051] In some embodiments, the frame 1 is further provided with a second slide rail 9, which is located on the side of the tube pressing assembly 4 away from the tube workpiece 2 to be pressed, a second slider 10 is slidably mounted on the second slide rail 9, and the first drive assembly 5 is mounted on the second slider 10. The second slide rail 9 of this embodiment is fixed on the frame 1, and the second slide rail 9 is located on the side of the tube pressing assembly 4 away from the tube workpiece 2 to be pressed, and a plurality of second sliders 10 are slidably mounted on the second slide rail 9 of this embodiment. Preferably, two second slide rails 9 are provided on the frame 1 of this embodiment, and two second sliders 10 are slidably mounted on each second slide rail 9, and this embodiment can effectively improve the stability of driving the first drive assembly 5 to move. Since the driving direction of the third drive assembly 8 is perpendicular to the driving direction of the first drive assembly 5, the extension direction of the first slide rail 19 of this embodiment is perpendicular to the extension direction of the second slide rail 9.

[0052] In some embodiments, both sides of the second slide rail 9 are provided with limit blocks 14. In this embodiment, both sides of the second slide rail 9 are provided with limit blocks 14, so this embodiment can limit the sliding position of the first drive assembly 5, thereby effectively avoiding the situation where the connector 17 slides out of the slot 42 due to excessive movement of the first drive assembly 5. Preferably, the limit blocks 14 of this embodiment are provided with hydraulic buffers 15 and polyurethane stoppers 16, and the hydraulic buffers 15 and polyurethane stoppers 16 can both play a role in preventing the first drive assembly 5 from directly contacting the limit blocks 14, so this embodiment can effectively avoid the situation where the first drive assembly 5 and the limit blocks 14 are damaged or even destroyed due to direct contact between the first drive assembly 5 and the limit blocks 14.

[0053] In some embodiments, a sensing bracket 11 is fixed to one side of the first driving component 5 close to the pressing tube component 4, and a first in-place detection component 12 and a second in-place detection component 13 are provided between the first driving component 5 and the pressing head 41. The first in-place detection component 12 and the second in-place detection component 13 of this embodiment can be components such as photoelectric switches or photoelectric sensors that can detect whether an object is in place. Specifically, when the sensing bracket 11 moves to the first in-place detection component 12, the connector 17 is moved to the card slot 42 of the pressing head 41 close to the third driving component 8, and when the sensing bracket 11 moves to the second in-place detection component 13, the connector 17 is moved to the card slot 42 of the pressing head 41 away from the third driving component 8. Therefore, the first in-place detection component 12 of this embodiment is used to detect whether the connector 17 moves to the card slot 42 of the pressing head 41 close to the third driving component 8, and the second in-place detection component 13 of this embodiment is used to detect whether the connector 17 moves to the card slot 42 of the pressing head 41 away from the third driving component 8.

[0054] In some embodiments, the tightening assembly 6 includes a floating support cylinder base 61, which is slidably mounted on the frame 1, and a plurality of floating support cylinders 62 are mounted on the side of the floating support cylinder base 61 close to the pipe workpiece 2 to be pressed, and the second driving assembly 7 is connected to the floating support cylinder base 61. The floating support cylinder base 61 of this embodiment is slidably mounted on the frame 1, that is, the floating support cylinder base 61 can slide relative to the frame 1, and a plurality of floating support cylinders 62 are mounted on the side of the floating support cylinder base 61 close to the pipe workpiece 2 to be pressed, and the floating support cylinder 62 can be an existing pneumatic floating support cylinder or a hydraulic floating support cylinder. The floating support cylinder 62 of this embodiment is preferably a hydraulic floating support cylinder. After the hydraulic oil enters the cylinder body of the floating support cylinder 62, the piston end of the floating support cylinder 62 will extend and contact the pipe workpiece 2 to be pressed.

[0055] In some embodiments, the number of floating support cylinders 62 is two, and the two floating support cylinders 62 are symmetrically installed on the floating support cylinder base 61 with the center of the floating support cylinder base 61 as the symmetry center. Since the number of floating support cylinders 62 in this embodiment is two, that is, the jacking assembly 6 in this embodiment is equivalent to contacting two positions of the pipe workpiece 2 to be pressed at the same time, so that the force on the pipe workpiece 2 to be pressed is more uniform, and therefore this embodiment can effectively improve the jacking effect of the jacking assembly 6.

[0056] In some embodiments, the pipe pressing machine with the function of preventing the workpiece from shifting further includes a second limit assembly 23, which is mounted on the frame 1 and is used to lock the position of the floating support cylinder base 61. The second limit assembly 23 of this embodiment may be a limit head or a limit rod or other assembly that can lock the position of the floating support cylinder base 61. Since the second limit assembly 23 of this embodiment can block the clamping assembly 6 from moving in a direction away from the pipe workpiece 2 to be pressed, this embodiment can effectively avoid the situation where the clamping assembly 6 and the second drive assembly 7 cannot limit the position of the pipe workpiece 2 to be pressed away from one end of the first drive assembly 5 due to the excessive force provided by the first drive assembly 5 and the pipe pressing assembly 4 to the pipe workpiece 4, resulting in the displacement of the pipe workpiece 2 to be pressed in the pressing direction of the pipe 21, that is, this embodiment can further improve the clamping effect of the clamping assembly 6.

[0057] In some embodiments, second positioning holes 24 are provided on both sides of the floating cylinder base 61, and the second limiting assembly 23 includes a third cylinder 2301 and a fourth cylinder 2302, and the third cylinder 2301 and the fourth cylinder 2302 are respectively installed on both sides of the floating cylinder base 61, and the piston ends of the third cylinder 2301 and the fourth cylinder 2302 are fixed with second positioning heads, and the third cylinder 2301 and the fourth cylinder 2302 can both insert the second positioning heads into the second positioning holes 24. Specifically, after the second driving assembly 7 drives the floating cylinder base 61 to move toward the pipe workpiece 2 to be pressed, the third cylinder 2301 and the fourth cylinder 2302 of this embodiment drive the second positioning head to move toward the floating cylinder base 61 to insert the second positioning head into the second positioning hole 24. After all the pipes 21 are pressed into the pipe workpiece 2 to be pressed, this embodiment first controls the third cylinder 2301 and the fourth cylinder 2302 to drive the second positioning head to move away from the floating cylinder base 61 to move the second positioning head out of the second positioning hole 24, and then controls the second driving assembly 7 to drive the floating cylinder base 61 to move away from the pressed pipe workpiece.

[0058] As can be seen from the above, the utility model provides a pipe pressing machine with the function of preventing workpiece displacement, including a frame 1, a clamping assembly 3, a pipe pressing assembly 4, a first drive assembly 5, a clamping assembly 6 and a second drive assembly 7. Since the pipe pressing assembly 4 and the first drive assembly 5 as well as the clamping assembly 6 and the second drive assembly 7 are respectively arranged on both sides of the pipe workpiece 2 to be pressed, and during the pipe pressing process, the clamping assembly 6 can limit the position of the pipe workpiece 2 to be pressed away from one end of the first drive assembly 5 to ensure that the pipe workpiece 2 to be pressed does not move along the pressing direction of the pipe 21. Therefore, when the pipe 21 is pressed into the pipe workpiece 2 to be pressed, even if the vertical force provided by the clamping assembly 3 is insufficient, the present application will not cause the pipe workpiece 2 to be pressed to shift along the pressing direction of the pipe 21, that is, the present application can completely press the pipe 21 into the pipe workpiece 2 to be pressed, that is, the present application can effectively solve the problem of the pipe 21 not being pressed into place or the pipe 21 failing to be pressed due to the displacement of the pipe workpiece 2 to be pressed along the pressing direction of the pipe 21 during the pipe pressing process.
