Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing equipment, in particular to a torsion rubber core shaft tube positioning and cutting device. Background Art

[0002] The torsion rubber core shaft acts on both ends of the torsion bar of the automobile chassis bridge, and plays the role of shock absorption and buffering as well as guiding and transmitting force. The existing torsion rubber core includes an outer sleeve, two rubber baffles, two external fixed baffles, an elastic rubber body and a central shaft. The torsion rubber core can provide additional friction and damping effect to prevent the threaded connection from loosening by itself under vibration or vibration conditions. The torsion rubber core can increase the tightening force of the threaded connection, making the connection more firm and reliable. It is suitable for applications that need to prevent loosening and oil leakage, such as automobile engines, pipeline connections, etc. The torsion rubber core usually has chemical corrosion resistance and can be used in harsh environments. In general, the torsion rubber core can provide stronger connection strength, prevent loosening and oil leakage, and is suitable for various application scenarios. In the production process of the torsion rubber core shaft tube, it needs to be cut to facilitate subsequent installation and use. The existing cutting work is generally performed manually, which is inefficient and labor-intensive, so a new cutting device is needed. Summary of the invention

[0003] Other features and advantages of the present invention will be described in the following description, and partly become apparent from the description, or be understood by implementing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the description and other drawings of the description.

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a torsion rubber core shaft tube positioning and cutting device.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a torsion rubber core shaft tube positioning and cutting device, comprising a frame and a cutting mechanism, the frame is rotatably connected to a turntable under the cutting mechanism, the frame is provided with a shifting mechanism for driving the turntable to rotate, the side of the turntable has four working surfaces, the turntable is slidably connected with a clamping piece for clamping the pipe fitting on the working surface at each of the working surfaces, the turntable is provided with a lifting mechanism for changing the distance between the clamping piece and the working surface at each working surface, the frame is provided with a control mechanism for controlling the operation of the lifting mechanism, the control mechanism is provided with two groups, and the two groups of control mechanisms respectively control the lifting mechanisms on two adjacent working surfaces, the frame is provided with a loading mechanism for pushing the pipe fitting to be inserted between the clamping piece and the working surface and a unloading mechanism for pushing the pipe fitting out of the turntable, and the turntable is provided with a positioning mechanism for limiting the cutting length of the pipe fitting.

[0006] By adopting the above technical solution, the turntable can be driven to rotate intermittently by using the transposition mechanism to switch the working surface. The working surface at the top is responsible for cutting. In the initial state, the clamping piece is at the highest point under the action of the lifting mechanism. At this time, the distance between the clamping piece and the working surface is the largest. The pipe fitting is inserted between the working surface and the clamping piece under the action of the feeding mechanism. After the pipe fitting enters between the working surface and the clamping piece, it will be blocked by the positioning mechanism, causing the feeding mechanism to stop working, thereby controlling the cutting length. Then the control mechanism works to drive the lifting mechanism to move, so that the clamping piece moves downward to clamp the pipe fitting. Then the cutting mechanism cuts the pipe fitting under the drive of the lifting cylinders on both sides of the frame. After the cutting is completed, the cutting mechanism is lifted and reset. At this time, the transposition mechanism works to drive the turntable to rotate, so that the other working surface moves to the top of the turntable, and the original working surface moves with the cut pipe fitting. On the side of the turntable, the two control mechanisms work simultaneously, driving the clamping parts at the top to continue clamping the pipe fittings fed in by the feeding mechanism, while the clamping parts holding the cut pipe fittings are lifted upward by the joint action of the control mechanism and the lifting mechanism to release the clamping of the pipe fittings. At this time, the pipe fittings may detach from the turntable under the action of their own weight, or they may not detach due to the friction factor. At this time, the turntable rotates again, and the unfixed pipe fittings move to the bottom of the turntable. At this time, the pipe fittings fall on the clamping parts under the action of their own weight and at the same time break away from the limit of the positioning mechanism. At this time, the unloading mechanism pushes the pipe fittings out of the turntable to realize unloading. The feeding mechanism, control mechanism, lifting mechanism, unloading mechanism, cutting mechanism and transposing mechanism are used in a sequential cyclic action to cut the long pipe fittings into several short pipe fittings of the required length for processing the shaft tube. This method can effectively improve the processing efficiency and save manpower.

Specifically, the position of the connecting piece can be changed by screw rod two, and when the slider moves under the drive of screw rod one, it can push the pushing plate to push the connecting piece, so that the sliding frame overcomes the elastic force of the spring to slide, thereby making the sliding frame drive the driving rod to slide, and when the position of the connecting piece changes, the spacing between the pushing plate and the connecting piece also changes. Therefore, in the process of moving the same distance, the pushing plate can push the distance of the connecting piece to change accordingly, thereby changing the movement distance of the driving rod, so that the driving plate drives the clamping piece to descend to an adjustable height, and when the pushing plate is reset, the spring releases the elastic force to provide the power required for the reset of the sliding frame, thereby driving the driving rod to lift the clamping piece to the highest point.

[0030] like Figure 1-4 As shown, a torsion rubber core shaft tube positioning and cutting device includes a frame 1 and a cutting mechanism 2. The frame 1 is rotatably connected to a turntable 3 below the cutting mechanism 2. The frame 1 is provided with a transposition mechanism for driving the turntable 3 to rotate. The side of the turntable 3 has four working surfaces 4. The turntable 3 is slidably connected to a clamping member 5 for clamping the pipe fitting on the working surface 4 at each working surface 4. The turntable 3 is provided with a lifting mechanism for changing the distance between the clamping member 5 and the working surface 4 at each working surface 4. The frame 1 is provided with a control mechanism for controlling the operation of the lifting mechanism. The control mechanism is provided with two groups, and the two groups of control mechanisms respectively control the lifting mechanisms on two adjacent working surfaces 4. The frame 1 is provided with a loading mechanism for pushing the pipe fitting to be inserted between the clamping member 5 and the working surface 4 and a unloading mechanism for pushing the pipe fitting out of the turntable 3. The turntable 3 is provided with a positioning mechanism for limiting the cutting length of the pipe fitting.

[0031] By adopting the above technical solution, the turntable 3 can be driven to rotate intermittently by using the transposition mechanism to switch the working surface 4. The working surface 4 at the top is responsible for cutting. In the initial state, the clamping member 5 is at the highest point under the action of the lifting mechanism. At this time, the distance between the clamping member 5 and the working surface 4 is the largest. The pipe is inserted between the working surface 4 and the clamping member 5 under the action of the feeding mechanism. After the pipe enters between the working surface 4 and the clamping member 5, it will be blocked by the positioning mechanism, causing the feeding mechanism to stop working, thereby controlling the cutting length. Then the control mechanism works to drive the lifting mechanism to move, so that the clamping member 5 moves downward to clamp the pipe. Then the cutting mechanism 2 cuts the pipe under the drive of the lifting cylinders on both sides of the frame 1. After the cutting is completed, the cutting mechanism 2 is lifted and reset. At this time, the transposition mechanism works to drive the turntable 3 to rotate, so that the other working surface 4 moves to the top of the turntable 3, and the original working surface 4 is completed with cutting. The pipe moving turntable 3 moves to the side of the pipe fitting, and at this time, the two control mechanisms work simultaneously, driving the clamping member 5 at the top to continue clamping the pipe fitting fed in by the feeding mechanism, while the clamping member 5 holding the pipe fitting whose cutting is completed is lifted upward under the joint action of the control mechanism and the lifting mechanism, and the clamping of the pipe fitting is released. At this time, the pipe fitting may be separated from the turntable 3 under the action of its own weight, or it may not be separated due to the factor of friction. At this time, the turntable 3 rotates again, and the unfixed pipe fitting moves to the bottom of the turntable 3. At this time, the pipe fitting falls on the clamping member 5 under the action of its own weight, and at the same time breaks away from the limit of the positioning mechanism. At this time, the unloading mechanism pushes the pipe fitting out of the turntable 3 to realize unloading. The feeding mechanism, the control mechanism, the lifting mechanism, the unloading mechanism, the cutting mechanism 2 and the transposition mechanism are used in a sequential cyclic action to cut the long pipe fitting into a number of short pipe fittings of the required length for processing the shaft pipe. This method can effectively improve the processing efficiency and save manpower.

[0032] The lifting mechanism includes a driving plate 6, a driving rod 7, a slider 8 and a screw 9. The driving plate 6 is slidably connected to the turntable 3, the driving plate 6 is fixedly connected to the clamping member 5, the driving plate 6 is provided with an inclined slot 10, the driving rod 7 is inserted into the inclined slot 10, the screw 9 is rotatably connected to the turntable 3, the slider 8 is threadedly connected to the screw 9, and the driving rod 7 is connected to the slider 8. The rotation of the screw 9 can drive the slider 8 to slide through the thread pair, and the sliding of the slider 8 can drive the driving rod 7 to slide in the inclined slot 10. Since the height of the driving rod 7 itself does not change, the driving plate 6 will be lifted or lowered under the action of the inclined slot 10, thereby realizing the lifting and lowering of the clamping member 5.

[0033] The driving rod 7 is connected to the slider 8 through an adjusting mechanism, and the adjusting mechanism includes a sliding frame 11, a push plate 12, a connecting member 13 and a second screw 14. The sliding frame 11 is slidably connected to the turntable 3, the connecting member 13 is slidably connected to the sliding frame 11, the second screw 14 is rotatably connected to the sliding frame 11, the connecting member 13 is threadedly connected to the second screw 14, the push plate 12 is fixedly connected to the slider 8, the connecting member 13 abuts against the push plate 12, the sliding frame 11 is fixedly connected to the driving rod 7, and a spring 15 is arranged between the sliding frame 11 and the turntable 3. The adjusting mechanism can be used to adjust the sliding distance of the driving rod 7, thereby adjusting the distance of the clamping member 5 when it descends, so as to adapt to pipes of different diameters. The specific method is that the position of the connecting member 13 can be changed by the screw rod 2 14. When the slider 8 moves under the drive of the screw rod 1 9, it can push the push plate 12 to push the connecting member 13, so that the sliding frame 11 overcomes the elastic force of the spring 15 to slide, thereby making the sliding frame 11 drive the driving rod 7 to slide, and when the position of the connecting member 13 changes, the spacing between the push plate 12 and the connecting member 13 also changes. Therefore, when the push plate 12 moves the same distance, the distance that the connecting member 13 can be pushed also changes accordingly, thereby changing the movement distance of the driving rod 7, so that the driving plate 6 drives the clamping member 5 to descend to an adjustable height, and when the push plate 12 is reset, the spring 15 releases the elastic force to provide the power required for the reset of the sliding frame 11, driving the driving rod 7 to lift the clamping member 5 to the highest point.

[0034] The two sets of control mechanisms include a rotating rod 16 and a recessed block 18. One end of each of the four screw rods 9 is fixedly connected to an insert block 17. The recessed block 18 is fixedly connected to one end of the rotating rod 16. The recessed block 18 is provided with a slot matching the shape of the insert block 17. The insert block 17 is inserted into the slot. The insert block 17 is transmission-connected to the recessed block 18 via the slot. The rotating rod 16 is slidingly and rotationally connected to the frame 1. The frame 1 is provided with a driving mechanism for driving the rotating rod 16 to rotate and slide. The driving mechanism can drive the rotating rod 16 to slide and rotate in sequence. During the driving process, the rotating rod 16 first slides under the drive of the driving mechanism so that the concave block 18 at the end cooperates with the plug block 17 to form a transmission connection relationship between the screw 9 and the rotating rod 16. Then the driving mechanism drives the rotating rod 16 to rotate, thereby driving the screw 9 to rotate to realize the lifting and lowering of the clamping member 5. The rotating rods 16 on the two sets of control mechanisms rotate in opposite directions. One controls the clamping member 5 to descend and clamp the pipe fitting, and the other rotates in the opposite direction to control the clamping member 5 to rise and release the fixation. The two rotating rods 16 act synchronously.

[0035] The driving mechanism includes a push frame 19 and a cylinder 20. The push frame 19 is slidably connected to the frame 1. The rotating rods 16 on the two control mechanisms are rotatably connected to the push frame 19. The push frame 19 is provided with a power mechanism for driving the two rotating rods 16 to rotate. The cylinder 20 is fixedly connected to the frame 1, and the output rod of the cylinder 20 is transmission-connected to the push frame 19. The rope of the output rod of the cylinder 20 drives the push frame 19 to slide, thereby realizing the synchronous sliding of the two rotating rods 16.

[0036] The power mechanism includes a servo motor 21, two gears 22 and two pulleys 23, wherein one gear 22 is connected to one of the rotating rods 16, and the other gear 22 is connected to the output shaft of the servo motor 21, the two gears 22 are meshed with each other, one pulley 23 is connected to the other rotating rod 16, and the other pulley 23 is connected to the output shaft of the servo motor 21, and the two pulleys 23 are connected to each other through belts. The servo motor 21 provides the power required for the two rotating rods 16 to rotate, wherein one rotating rod 16 is driven by the servo motor 21 through the two gears 22, so that the rotation direction of the rotating rod 16 is opposite to the rotation direction of the output shaft of the servo motor, and the other rotating rod 16 is driven by the servo motor 21 through the two pulleys 23, so that the rotation direction of the rotating rod 16 is the same as the rotation direction of the output shaft of the servo motor 21, in this way, the rotation directions of the two rotating rods 16 are opposite, so that the two rotating rods 16 can respectively control the lifting and lowering of the clamping member 5.

[0037] The unloading mechanism includes a push rod 24 and a push member 25, wherein the push member 25 is fixedly connected to the end of the push rod 24, and the push rod 24 is fixedly connected to the push frame 19. By fixing the push rod 24 to the push frame 19, the push rod 24 can drive the push member 25 to push the pipe fitting out of the clamping member 5 as the push frame 19 slides.

[0038] The feeding mechanism includes two drive groups, which are symmetrically arranged. Both drive groups include a support frame 26, a drive wheel 27, a drive motor 28 and a cylinder 29. The cylinder 29 is fixedly connected to the frame 1, the support frame 26 is fixedly connected to the output rod of the cylinder 29, the drive wheel 27 is rotatably connected to the support frame 26, the drive motor 28 is fixedly connected to the support frame 26, and the output shaft of the drive motor 28 is transmission-connected to the drive wheel 27. The two drive groups are symmetrically arranged, so the output rods of the two cylinders 29 are extended toward the center line direction of the frame 1. During the extension process, the driving wheel 27 on the support frame 26 is driven to move toward the middle of the surface of the frame 1, so that the pipe fittings can be clamped in the middle of the frame 1 by the driving wheels 27 on the two drive groups, and at the same time align with the interval between the clamping piece 5 and the working surface 4. The driving motor 28 drives the driving wheel 27 to rotate through a belt drive, and continuously pushes the pipe fittings forward through friction to realize the feeding of the pipe fittings. The driving motor 28 is a pneumatic motor, which can be blocked by accessories such as a pressure relief valve so that the motor will not be damaged. Through this feature, the feeding mechanism will not be damaged after the pipe fittings are blocked by the positioning mechanism.

[0039] The positioning mechanism includes a fixing frame 31 and four baffles 30. The four baffles 30 are respectively arranged at four working surfaces 4. The fixing frame 31 is slidably connected to the turntable 3. The four baffles 30 are fixedly connected to the fixing frame 31. The turntable 3 is threadedly connected with a screw rod 32. The fixing frame 31 is rotatably connected to the screw rod 32. The four baffles 30 can be used to block the pipe fittings, thereby controlling the length of the pipe fitting cutting. The screw rod 32 is threadedly connected to the turntable 3, so that the fixing frame 31 can be driven to slide when the screw rod 32 rotates, thereby changing the positions of all the baffles 30. In this way, the length of the pipe fitting cutting can be adjusted.
