[0001] This utility model relates to the technical field of differential feed pipe cutting machine, specifically to a differential feed device and a differential feed pipe cutting machine. Background Technology

[0002] With the development of technology, production machinery in different industries has undergone various improvements, and many excellent production equipment has been proposed to meet higher production demands. In the field of pipe cutting, differential feed pipe cutting machines are commonly used. However, the differential feed pipe cutting mechanism of current differential feed pipe cutting machines usually uses a cylinder to push the cutter during pipe cutting. This method not only makes the overall differential feed pipe cutting machine larger and more space-consuming, but also results in lower cutting accuracy and ease of cutting. Utility Model Content

[0003] Therefore, this utility model provides a differential feed device and a differential feed pipe cutter, making the overall differential pipe cutter more compact and the cutting more efficient and precise.

[0004] To address the aforementioned problems, this utility model provides a differential feed device, comprising: a plate with a first receiving area; a tube clamping assembly disposed on the plate and used to clamp the tube to be processed to the first receiving area; a first rotating assembly disposed on the plate; a second rotating assembly connected to the first rotating assembly; a power assembly including two motors respectively driving and connecting the first and second rotating assemblies; and a tool control assembly connected to the first and second rotating assemblies, with a cutting element provided on the tool control assembly. Through the cooperation of the two motors, the first and second rotating assemblies rotate at different speeds, driving the tool control assembly to achieve linear differential feed or linear differential retraction.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: By incorporating a tube clamping assembly into the plate, the tube to be processed becomes more stable during processing. Simultaneously, the first and second rotating components rotate at different speeds in cooperation with two motors, allowing the tool control component to perform more stable linear feed or retraction under the differential rotation of the first and second rotating components. This configuration results in a more stable cutting rate and higher cutting precision. Furthermore, the coordination between these components makes the equipment smaller than traditional cutting equipment, simplifying operation. The mechanical connections between components have a lower failure rate compared to current signal or electronic connections, ensuring better normal operation and extending the equipment's lifespan, while also reducing costs.

[0006] In one embodiment of this utility model, the rotational speed of the first rotating component is defined as V1, and the rotational direction is a first direction; the rotational speed of the second rotating component is defined as V2, and the rotational direction is a second direction; wherein, V1 is greater than V2, and when the first direction and the second direction are the same, the tool control component drives the cutting part to achieve linear rapid tool feed or tool feed; and / or V1 is less than V2, and when the first direction and the second direction are the same, the tool control component drives the cutting part to achieve linear rapid tool retraction or tool retraction; wherein, V1 and V2 are controlled by two motor units to achieve differential speed.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: By setting up two motor units to control the rotational speed difference between the first and second rotating components, linear differential feed and retraction can be achieved. This not only simplifies the structure and connection, but also reduces the failure rate due to the mechanical connection method. The structure is also smaller, which effectively reduces maintenance costs, makes cutting more convenient and faster, and improves precision and practicality.

[0008] In one embodiment of this utility model, the knife control assembly further includes: a first fixing member, which is disposed on the side of the second rotating assembly away from the first rotating assembly; a first connecting part, which connects to the first rotating assembly and passes through the second rotating assembly and the first fixing member; and a second connecting part, which connects the first fixing member and the first connecting part, and is provided with a cutting member, and can be moved by the first connecting part.

[0009] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting the first fixing part as the base of the second connecting part, the installation of the second connecting part is more convenient. At the same time, the coordinated setting of the first and second connecting parts makes the driving method of the cutting part more mechanized, thereby avoiding electronic connection failures and extending the service life. In addition, the simplification of the linkage structure makes the device more compact and convenient to use, and the cost of subsequent maintenance is also lower.

[0010] In one embodiment of this utility model, the second rotating component is provided with a first limiting groove; the first fixing member is provided with a second limiting groove, and the first limiting groove is provided corresponding to the second limiting groove; wherein, the first connecting part passes through the first limiting groove and the second limiting groove.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: by setting the first limiting groove and the second limiting groove to be correspondingly set, the first connecting part passes through the two limiting grooves, and the first limiting groove and the second limiting groove form a restriction on the movement position of the first connecting part, so that the movement path of the first connecting part is fixedly guided when it is driven by the first rotating component, thereby ensuring the subsequent linkage of the second connecting part, and thus making the straight-line cutting and retraction of the cutting part more stable.

[0012] In one embodiment of this utility model, the first connecting part further includes: a connecting post, which is detachably connected to the first rotating component and passes through the first limiting groove and the second limiting groove; and a mating part, which connects the connecting post and the second connecting part.

[0013] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting the connecting column to be detachably set on the first rotating component, it is possible to replace it in time when it is damaged. At the same time, the setting of the mating part to cooperate with the connecting column makes the connection between the first connecting part and the second connecting part simpler, thereby reducing the connection failure rate.

[0014] In one embodiment of this utility model, the second connecting part further includes: a guide rail, which is disposed on the first fixing member; a sliding member, which is slidably disposed on the guide rail and connected to a mating member, so that when the connecting column pulls the mating member to move, it drives the sliding member to slide along the guide rail; wherein, the sliding member is provided with a cutting member.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting a guide rail on the first fixed part and setting a sliding part to cooperate with the guide rail, the feed path of the cutting part set on the sliding part is controlled and restricted, which can ensure the linear differential feed of the cutting part and make the feed more stable.

[0016] In one embodiment of this utility model, the slider is arched, and the lower part of the arch corresponds to the first receiving area.

[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting the sliding member to be arched, and with the lower part of the arch corresponding to the first receiving area, the sliding member will not affect the placement and processing of the tube to be processed, and the arched setting can better support the cutting part, ensuring the normal cutting of the cutting part.

[0018] In one embodiment of this utility model, the tube clamping assembly further includes: a first fixing part, which is connected to a plate; a plurality of rotating cam parts, which are circumferentially disposed on the first fixing part; a rotating wheel, which is provided with a plurality of sliding grooves, which are provided corresponding to the plurality of rotating cam parts, and the plurality of rotating cam parts at least partially pass through the plurality of sliding grooves; wherein, the plurality of rotating cam parts are driven by the rotating wheel to move toward the center position of the first fixing part to fix the tube to be processed.

[0019] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting multiple rotating cams in conjunction with rotating wheels, a clamping device with controllable pipe diameter is realized, which can be compatible when processing pipes of different diameters, thus improving the practicality and compatibility of the device. At the same time, by setting the rotating wheels and multiple rotating cams to be mechanically connected, the failure rate is lower and the service life is longer.

[0020] This utility model also provides a differential feed pipe cutter, which includes a differential feed device as described above.

[0021] Differential feed pipe cutting machines include any of the differential feed devices mentioned above, and therefore have the same technical effect, which will not be elaborated here.

[0022] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0023] (1) By setting the plate body to have a tube clamping assembly, the tube to be processed can be more stable during processing. At the same time, the first rotating assembly and the second rotating assembly are set to rotate at different speeds in cooperation with the two motors, so that the control assembly can perform more stable linear feed or retraction under the differential rotation of the first rotating assembly and the second rotating assembly. Through this setting, the cutting speed of the cutter is more stable and the cutting accuracy is higher. At the same time, by setting the cooperation between the above components, the size of the cutting equipment is smaller than that of traditional cutting equipment, so the operation of the equipment is simpler. At the same time, the mechanical connection between the components has a lower failure rate than the current signal connection or electronic connection, so as to better ensure the normal operation of the equipment. The service life of the equipment is longer and the corresponding cost is lower.

[0024] (2) By setting two motors to control the rotational differential of the first rotating component and the second rotating component, linear differential feed and retraction can be achieved. The structure is simple and the connection is simple. The mechanical connection method makes the failure rate lower and the structure smaller. This effectively reduces maintenance costs and makes cutting more convenient and faster, while also increasing precision and practicality. Attached Figure Description

[0034] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] [First Embodiment]

[0036] See Figures 1-6 This utility model provides a differential feed device 100, characterized in that the differential feed device 100 includes: a plate 110, the plate 110 having a first receiving area 111; a tube clamping assembly 120, the tube clamping assembly 120 being disposed on the plate 110 and used to clamp the tube to be processed to the first receiving area 111; a first rotating assembly 130, the first rotating assembly 130 being disposed on the plate 110; a second rotating assembly 140, the second rotating assembly 140 being connected to the first rotating assembly 130; and a power source. The power assembly 150 includes two motors that drive and connect the first rotating assembly 130 and the second rotating assembly 140 respectively; the tool control assembly 160 is connected to the first rotating assembly 130 and the second rotating assembly 140, and the tool control assembly 160 is provided with a cutting element 170; wherein, through the cooperation of the two motors, the first rotating assembly 130 and the second rotating assembly 140 rotate at different speeds, driving the tool control assembly 160 to achieve linear differential feed action or linear differential retraction action.

[0037] Specifically, in use, the pipe is first fixed to the pipe clamping assembly 120 of the plate 110. The pipe clamping assembly 120 can be a clamp with multiple rotating cams controlled by a motor. When the pipe clamping assembly 120 is started, the motor drives the multiple rotating cams to move toward the pipe, thereby fixing the pipe. Then, the power assembly 150 is started. The two motors of the power assembly 150 can be servo motors. The plate 110 of the first rotating assembly 130 and the second rotating assembly 140 can be gears. The connection with the motor can be a belt or a rack. Here, a gear is used as an example. The power assembly 150 can be started by an externally set button or by signal transmission.

[0038] Furthermore, specifically, the two motors use electronic cams to generate differential speed. The differential rotation between the first rotating component 130 and the second rotating component 140 is achieved through the control of the two motors. Due to the difference in rotational speed between the two rotating components, when the first rotating component 130 drives the first connecting part 162 to operate, the second rotating component 140 also drives the second connecting part 163 to operate. However, since the first connecting part 162 and the second connecting part 163 are connected, the sliding member 163b is subjected to the tension of the mating part 162b, which causes the cutting member 170 set on the sliding member 163b to move towards the first receiving area 111, thereby cutting the pipe. At the same time, due to the existence of differential speed, the cutting method is more stable and precise, and the feed does not require pushing. Differential feed is achieved through a simple linkage structure, which ensures stability while reducing structure and cost.

[0039] The connection between the components can be a bolted connection, a plug-in connection, or an embedded connection. Each component connection point is provided with bolt holes for bolt connection, which are not illustrated in this application.

[0040] Preferably, by providing a tube clamping assembly 120 on the plate 110, the tube to be processed can be more stable during processing. Simultaneously, the first rotating assembly 130 and the second rotating assembly 140 rotate at different speeds in cooperation with two motor units. This allows the tool control assembly 160 to perform more stable linear feed or retraction under the differential rotation of the first rotating assembly 130 and the second rotating assembly 140. This configuration makes the cutting rate of the cutting part 170 more stable and the cutting accuracy higher. Furthermore, by configuring the cooperation between the above components, the size of the equipment is smaller than that of traditional cutting equipment, making the operation simpler. The mechanical connections between the components have a lower failure rate than current signal or electronic connections, thus better ensuring the normal operation of the equipment, extending its service life, and correspondingly reducing costs.

[0041] Specifically, the rotational speed of the first rotating component 130 is defined as V1, and the rotational direction is the first direction; the rotational speed of the second rotating component 140 is defined as V2, and the rotational direction is the second direction; wherein, V1 is greater than V2, and when the first direction and the second direction are the same, the tool control component 160 drives the cutting component 170 to achieve linear rapid tool feed or tool feed; and / or V1 is less than V2, and when the first direction and the second direction are the same, the tool control component 160 drives the cutting component 170 to achieve linear rapid tool retraction or tool retraction; wherein, V1 and V2 are controlled by two motor units to achieve differential speed.

[0042] Preferably, by setting two motor units to control the rotational differential of the first rotating component 130 and the second rotating component 140, linear differential feed and retraction can be achieved. This not only simplifies the structure and connection, but also reduces the failure rate and reduces the size of the structure, thereby effectively reducing maintenance costs and making cutting more convenient and faster, while also achieving higher precision and greater practicality.

[0043] Specifically, the knife control assembly 160 further includes: a first fixing member 161, which is located on the side of the second rotating assembly 140 away from the first rotating assembly 130; a first connecting part 162, which connects to the first rotating assembly 130 and passes through the second rotating assembly 140 and the first fixing member 161; and a second connecting part 163, which connects the first fixing member 161 and the first connecting part 162, and is provided with a cutting member 170, and can be moved by the first connecting part 162.

At the same time, by setting the first connecting part 162 and the second connecting part 163 in a coordinated manner, the driving method of the cutting part 170 is more mechanized, thereby avoiding electronic connection failures and extending the service life. Meanwhile, the simplification of the linkage structure makes the device more compact and convenient to use, and the cost of subsequent maintenance is also lower.

[0045] Specifically, the second rotating component 140 is provided with a first limiting groove 141; the first fixing member 161 is provided with a second limiting groove 161a, and the first limiting groove 141 is provided corresponding to the second limiting groove 161a; wherein, the first connecting part 162 passes through the first limiting groove 141 and the second limiting groove 161a.

[0046] Preferably, by setting the first limiting groove 141 and the second limiting groove 161a respectively, the first connecting part 162 passes through the two limiting grooves. The first limiting groove 141 and the second limiting groove 161a restrict the movement position of the first connecting part 162, so that the movement path of the first connecting part 162 is fixedly guided when it is driven by the first rotating component 130, thereby ensuring the subsequent linkage with the second connecting part 163, and making the linear feed and retraction of the cutting part 170 more stable.

[0047] Specifically, the first connecting part 162 further includes: a connecting post 162a, which is detachably connected to the first rotating assembly 130 and passes through the first limiting groove 141 and the second limiting groove 161a; and a mating part 162b, which connects the connecting post 162a and the second connecting part 163.

[0048] Preferably, by setting the connecting post 162a to be detachably mounted on the first rotating assembly 130, it is possible to replace it in time in case of subsequent damage. At the same time, a mating part 162b is set to cooperate with the connecting post 162a to make the connection between the first connecting part 162 and the second connecting part 163 simpler, thereby reducing the connection failure rate.

[0049] Specifically, the second connecting part 163 further includes: a guide rail 163a, which is disposed on the first fixing member 161; and a sliding member 163b, which is slidably disposed on the guide rail 163a and connected to the mating member 162b, so that when the connecting post 162a pulls the mating member 162b to move, it drives the sliding member 163b to slide along the guide rail; wherein, the sliding member 163b is provided with a cutting member 170.

[0050] Preferably, by setting the guide rail 163a on the first fixed member 161 and setting the sliding member 163b to cooperate with the guide rail 163a, the feed path of the cutting member 170 set on the sliding member 163b is controlled and restricted, which can ensure the linear differential feed of the cutting member 170, thereby making the feed more stable.

[0051] Specifically, the slider 163b is arched, and the lower part of the arch is set corresponding to the first receiving area 111.

[0052] Preferably, by setting the sliding member 163b to be arched, and the lower part of the arch corresponds to the first receiving area 111, the sliding member 163b will not affect the placement and processing of the tube to be processed, and the arched setting can better support the cutting member 170, ensuring the normal cutting of the cutting member 170.

[0053] Specifically, the clamping assembly 120 further includes: a first fixing part 121, a plate 110 of the first fixing part 121; a plurality of rotating cam parts 122, which are circumferentially disposed on the first fixing part 121; a rotating wheel 123, which is provided with a plurality of sliding grooves 124, which are provided corresponding to the plurality of rotating cam parts 122, and the plurality of rotating cam parts 122 at least partially pass through the plurality of sliding grooves 124; wherein, the plurality of rotating cam parts 122 are driven by the rotating wheel 123 to move toward the center position of the first fixing part 121 to fix the tube to be processed.

[0054] Preferably, by setting multiple rotating cams 122 in conjunction with rotating wheels 123, a clamping device with controllable pipe diameter is realized, which can be compatible when processing pipes of different diameters, improving the practicality and compatibility of the device. At the same time, by setting the rotating wheels 123 and multiple rotating cams 122 to be mechanically connected, the failure rate is lower and the service life is longer.
