Detailed Description
In order that the present invention may be more readily and clearly understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.
Fig. 3 is a schematic structural diagram of a traction device of an automatic pipe cutting machine according to an embodiment of the present application. Should include fixing base 1, linear guide 2, sliding seat 3, pinch roller subassembly 4 and drive assembly. The driving assembly can drive the sliding seat 3 to move along the linear guide rail 2, so that the plurality of pressing wheel assemblies 4 are driven to be close to or far away from each other, the plurality of pressing wheel assemblies 4 can be pressed on the outer sides of the pipe bodies with different sizes, and traction on the pipe bodies is achieved through friction force.
Specifically, a through hole 5 for the pipe body to pass through is formed in the middle of the fixing seat 1.
The linear guide 2 is fixedly arranged on the fixed seat 1. The linear guide 2 is provided with at least three. The linear guide rails 2 are located in the same plane, and the plane is parallel to the plane of the fixed seat 1. The included angles between any two adjacent linear guide rails 2 are equal.
Referring to fig. 3, in the present embodiment, the linear guide 2 is provided with three pieces. The included angle between two adjacent linear guide rails 2 is 120 degrees.
A sliding seat 3 is slidably mounted on each linear guide rail 2. The slide shoe 3 is reciprocally movable along the linear guide 2.
The number of the pinch roller assemblies 4 is the same as that of the linear guide rails 2. Each pinch roller assembly 4 is fixedly connected with the sliding seat 3 on the corresponding linear guide rail 2. Namely, when the sliding seat 3 moves along the linear guide rail 2, the pinch roller assembly 4 can be driven to move synchronously. The extension line of the center line of each pinch roller assembly penetrates through the center of the through hole.
The driving assembly is used for driving the sliding seat 3 to move along the linear guide rail 2, so that the pinch roller 13 assemblies 4 are close to or far away from each other. Wherein, the driving component comprises a driving wheel 6 which is rotatably arranged on the fixed seat 1 and a driving device which is used for the driving wheel 6 to rotate around the axis thereof. The drive wheel 6 is circular, see fig. 3. The axis of the driving wheel 6 coincides with the axis of the through hole 5 on the fixed seat 1. The driving wheel 6 is provided with slotted holes 7 with the same number as the pinch roller assemblies 4. The slotted holes 7 are arranged in a rotational symmetry mode by taking the circle center of the driving wheel 6 as a rotation center. Each slot 7 is arc-shaped, and the distance between one end of the arc and the circle center of the driving wheel 6 is larger than the distance between the other end of the arc and the circle center of the driving wheel 6. Each pinch roller assembly 4 is rotatably provided with a contact wheel 8, the contact wheel 8 is positioned in the adjacent slotted hole 7, and the diameter of the contact wheel 8 is equal to the width of the slotted hole 7. The wheel surface of the contact wheel 8 is attached to the inner wall of the slot hole 7.
When the driving wheel 6 rotates around the axis thereof, the slotted hole 7 on the driving wheel 6 rotates synchronously therewith. In the moving process of the slotted hole 7, thrust can be applied to the contact wheel 8 in the slotted hole 7 to drive the contact wheel 8 to move. Because the pinch roller 13 assembly 4 is fixedly connected with the sliding seat 3, and the sliding seat 3 can only slide along the length direction of the linear guide rail 2, the contact wheels 8 can only move along the length direction of the linear guide rail 2, and the moving directions of all the contact wheels 8 during moving are the same, namely, the contact wheels are close to or far away from each other. The contact wheel 8 drives the corresponding pinch roller assemblies 4 to move synchronously when moving, so that the pinch roller assemblies 4 move along the length direction of the linear guide rail 2, and all the pinch roller assemblies 4 are close to the center of the through hole 5 synchronously or far away from the center of the through hole 5 synchronously. So that the pinch roller assemblies 4 can clamp pipes with different sizes. And because a plurality of groups of pinch roller assemblies 4 are evenly pressed on the side wall of the tube body, the tube body can be stably clamped between the groups of pinch roller assemblies 4.
Referring to fig. 3, a plurality of positioning wheels 11 are rotatably mounted on the fixed base 1. The centers of the plurality of positioning wheels 11 are positioned on the same circumference, and the centers of the circles of the positioning wheels are superposed with the center of the driving wheel 6. The outer side surface of the driving wheel 6 is attached to the wheel surface of the positioning wheel 11. The positioning wheels 11 can limit the driving wheel 6 in the vertical direction, and ensure that the driving wheel 6 can only rotate around the axis of the driving wheel.
Preferably, the middle of the wheel surface of each positioning wheel 11 is provided with a positioning groove 12, see fig. 4. The width of the positioning slot 12 is equal to or slightly greater than the thickness of the driving wheel 6. The outer side surface of the driving wheel 6 extends into the positioning grooves 12 of the wheel surfaces of all the positioning wheels 11. The positioning groove 12 can limit the driving wheel 6 in the front-back direction, so that the driving wheel 6 can rotate in the same vertical plane all the time.
The drive means comprise a drive rod 9 and a drive element 10. The driving element 10 is in driving connection with the driving rod 9, and can drive the driving rod 9 to move along the length direction of the driving rod. Wherein, the driving element 10 is hinged with the fixed seat 1. The free end of the transmission rod 9 is hinged with the wheel surface of the transmission wheel 6. When the driving element 10 drives the transmission rod 9 to move along the length direction thereof, the transmission wheel 6 can be driven to rotate around the axis thereof.
It should be noted that at least one of the plurality of puck assemblies 4 is an active puck assembly. The rest of the pinch roller assemblies 4 are driven pinch roller assemblies. Compared with the driven pinch roller assembly, the driving pinch roller assembly also comprises a driving motor 15, and the driving motor 15 is in driving connection with any pinch roller 13 in the pinch roller assembly 4. When all the pressure wheel assemblies 4 are connected to the outer side of the pipe body in a pressure equalizing mode, the driving motor 15 in the active pressure wheel assembly can drive the pressure wheel 13 to rotate around the axis of the pressure wheel 13, and the pressure wheel 13 drives the other pressure wheel 13 to rotate synchronously through the transmission wheel belt 14. The friction between the pinch roller assembly 4 and the tube body can drive the tube body to move along the axis of the tube body. In the moving process of the pipe body, under the action of friction force, the transmission wheel surfaces 14 of the rest driven pinch roller assemblies also move, so that the driven pinch roller assemblies move synchronously.
It can be understood that all the pressure roller assemblies 4 can be active pressure roller assemblies, so that the traction effect on the pipe body is ensured, but the cost is higher.
From this, the technical scheme of this application can guarantee the effect that compresses tightly to the body of different materials, effectively avoids the body from the condition of deviating from between the pinch roller, simultaneously, applicable in not unidimensional body, application scope is wider.
In addition to the above embodiments, the present invention may have other embodiments; all technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
