In order to realize the clamping of the workpiece, the present technical solution provides a clamping mechanism including a frame body 441, a linear driving mechanism 45 and a clamping terminal 44, which can be used for clamping any suitable workpiece. The clamping mechanism comprises a frame body 441 and a clamping terminal 44, the frame body 441 is used for being fixedly connected or slidably connected with the whole machine, and the linear driving mechanism 45 is fixedly connected with the frame body 441; the clamping terminal 44 includes a pin 4423, a pair of connecting rods 4429, a pair of clamping blocks 442, and the like, the connecting rod 4429 is hinged to the clamping blocks 442 via a second hinge 4422, the linear driving mechanism 45 may be an oil cylinder, an electric push rod, or another mechanism capable of achieving linear driving, the linear driving mechanism in this embodiment employs an oil cylinder, and the oil cylinder is further provided with an oil pump, and a slider 4427 is further provided between a piston rod of the oil cylinder and the connecting rod 4429, the slider 4427 is provided in a linear sliding groove, and the slider 4427 can slide in the linear sliding groove under the driving of the oil cylinder. When a workpiece needs to be clamped, the oil cylinder extends out of the piston rod, the piston rod pushes the sliding block 4427 to move, the sliding block 4427 drives the connecting rod 4429 to act, the connecting rod 4429 drives the clamping blocks 442 to rotate around the pin rod 4423, the pair of clamping blocks 442 is folded, and then the pair of clamping blocks 442 clamps the workpiece. The frame body 441 is provided with a first strip-shaped hole 4424, the length direction of the first strip-shaped hole 4424 is arranged in the output direction of the linear driving mechanism 45, and the pin 4423 is arranged in the first strip-shaped hole 4424; the frame body 441 is provided with a connecting point at a side thereof remote from the pair of clips 442, and a pre-tensioned elastic member 46 is provided between the connecting point and the pin 4423. Positioning surfaces 4425 are disposed on the opposite sides of the pair of clips 442; when the pair of clips 442 are closed, the pair of positioning surfaces 4425 abut each other. The pre-tensioned elastic member 46 may be a tension spring or other elastic member capable of applying a tensile force to the pin 4423, and since the pin 4423 is under the tensile force of the pre-tensioned elastic member 46, when the workpiece is not clamped, the pin 4423 is located at the upper end of the first strip-shaped hole 4424, and when the thrust value of the cylinder is greater than the tensile force value applied to the pin 4423 by the pre-tensioned elastic member 46, the clamping block 442 and the pin 4423 slide downward along the first strip-shaped hole 4424 integrally, so that the pin 4423 moves to the lower end of the first strip-shaped hole 4424. As shown in fig. 6, when the clamping terminal 44 does not clamp the workpiece, the cylinder is in the piston rod retracted state, and the pair of clamping blocks 442 are opened by taking the pin 4423 as the rotation center under the driving of the pulling force of the pair of connecting rods 4429; when a workpiece needs to be clamped, the workpiece is placed in the clamping portion 4428 of the clamping block 442, the oil cylinder drives the oil cylinder to extend out of the piston rod, the piston rod drives the sliding block 4427 to slide along the sliding groove, the sliding block 4427 applies a pushing force to the connecting rod 4429, the pushing force value of the oil cylinder is smaller than the pulling force value applied to the pin rod 4423 by the pre-tensioning elastic piece 46, the pin rod 4423 is in a fixed state, the pair of connecting rods 4429 respectively drive the left clamping block 442 and the right clamping block 442 to rotate around the pin rod 4423, so that the pair of clamping blocks 442 rotate and close by the pin rod 4423, when the positioning surfaces 4425 of the two clamping blocks 442 are attached to each other, the pair of clamping blocks 442 are closed to the right, the clamping portions 4428 of the two clamping blocks 442 are closed to form a jaw, and the jaw clamps the workpiece, as shown in fig. 7. When the clamping mechanism clamps a workpiece and needs to attach the workpiece to another workpiece, the oil pump increases the oil pressure of the oil cylinder, increases the thrust force on the pair of connecting rods 4429, and the thrust force value of the oil cylinder is greater than the tension force value applied to the pin 4423 by the pre-tensioning elastic piece 46, so that the clamping block 442 and the pin 4423 integrally slide downwards along the first strip-shaped hole 4424, the pin 4423 is moved to the lower end of the first strip-shaped hole 4424, the clamped workpiece approaches the surface of another workpiece, and the clamped workpiece is attached to the surface of the another workpiece, so that an operator can weld the clamped workpiece to the surface of the another workpiece conveniently, as shown in fig. 8.
The oil cylinder drives the whole clamping terminal 44 to move along the first strip-shaped hole 4424, so that when the clamped workpiece is attached to the surface of another workpiece, the whole clamping terminal 44 can be regarded as a rigid body, and the stress condition of the rigid body is as follows: the rigid body is subjected to thrust exerted by the oil cylinder; the rigid body is subjected to a pulling force exerted by the pre-tensioned elastic element 46, which pulling force is directed opposite to the pushing force; the rigid body is subjected to a reaction thrust of the clamped workpiece, the reaction thrust being in the same direction as the pulling force. After the clamped workpiece is welded to the other workpiece surface, the operation of separating the clamping terminal 44 from the welded workpiece is as follows: the piston rod of the cylinder retracts, the piston rod drags the slide block 4427 to slide back along the sliding groove, the slide block 4427 applies a pushing force to the connecting rod 4429 to reduce and convert the pushing force into a pulling force, meanwhile, under the action of the pulling force of the pre-tensioning elastic element 46, the clamping terminal 44 tends to move upwards integrally, and the clamping terminal is always kept in a clamping state under the action of the pulling force of the pre-tensioning elastic element 46, and here, it should be noted that the magnitude of the clamping force between the two clamping blocks 442 is determined by the magnitude of the pulling force of the pre-tensioning elastic element 46 on the pin 4423 in the process of separating the clamping terminal 44 from the welded workpiece. The retraction amount of the piston rod of the oil cylinder is larger and larger, and the slider 4427 applies pulling force to the connecting rod 4429 to be increased gradually; when the magnitude of the pulling force is smaller than the magnitude of the pulling force of the pre-tensioned elastic member 46 on the pin 4423, the two clamping blocks 442 keep the state of clamping the welded workpiece; when the pulling force is equal to or greater than the pulling force of the pre-tensioning elastic element 46 on the pin 4423, the two clamping blocks 442 rotate around the pin 4423 under the pulling force of the connecting rod 4429, and the whole clamping terminal 44 starts to slide upwards along the first strip-shaped hole 4424, i.e. the opening of one side of the clamping terminal 44 moves upwards along the first strip-shaped hole 4424 until the opening of the clamping terminal 44 just allows the clamped workpiece to slide out of the clamping part 4428, and at the moment when the clamped workpiece slides out of the clamping part 4428, because the pin 4423 is located in the middle of the first strip-shaped hole 4424, the pin 4423 is forced to move towards the upper end of the first strip-shaped hole 4424 under the pulling force of the pre-tensioning elastic element 46, so that the two clamping blocks 442 are folded again. After the two clamping blocks 442 are folded again, the pin 4423 and the entire clamping terminal 44 slide upward along the first strip-shaped hole 4424 as the cylinder piston rod continues to retract, and during this sliding, the two clamping blocks 442 maintain a clamped state. When the pin 4423 moves to the end of the upper end of the first strip-shaped hole 4424, the pin 4423 and the whole clamping terminal 44 stop moving, and the piston rod of the oil cylinder continues to retract, at this time, under the pulling force of the connecting rod 4429, the two clamping blocks 442 rotate around the pin 4423 and are completely opened to wait for the clamping of the next clamped workpiece.
It should be noted that, in the process of opening one side of the clamping terminal 44 and moving upward along the first strip-shaped hole 4424, friction is generated between the inner wall of the clamping portion 4428 and the surface of the clamped workpiece, however, in the present technical solution, the clamping area where the inner wall of the clamping portion 4428 and the surface of the clamped workpiece act is small, and therefore the friction area between the inner wall of the clamping portion 4428 and the surface of the clamped workpiece is small and negligible. If the surface of the clamped workpiece has high roughness or smoothness, the friction between the inner wall of the clamping part 4428 and the surface of the clamped workpiece needs to be considered.
Compared with the prior art, the opening, closing and translation of the clamping mechanism generally adopt two relatively independent power sources and transmission mechanisms, the technical scheme is that the frame body 441 is provided with the first strip-shaped hole 4424, the pin rods 4423 hinged with the two clamping blocks 442 are inserted into the first strip-shaped hole 4424, the two ends of the pin rods 4423 are provided with the pre-tensioning elastic pieces 46 for applying tension to the pin rods 4423, and only one power source, namely the linear driving mechanism 45 is needed, so that four actions of clamping a workpiece to be fixed by the clamping terminal 44, transferring the clamped workpiece to be fixed by the clamping terminal 44 along the output shaft direction of the linear driving mechanism 45, separating the fixed workpiece from the clamping terminal 44 and recovering the opening state of the clamping terminal 44 can be realized, and the structure of the clamping mechanism is simplified.
It should be noted that, in the present embodiment, to realize four actions by only one driving source for the clamping terminal 44, the positions of the first hinge portion 4421 and the two second hinge portions 4422 must satisfy: the first hinge 4421 is located above the horizontal line connecting the two second hinges 4422. If the first hinge portion 4421 is located below the horizontal connecting line of the two second hinge portions 4422, the initial state before the workpiece is not clamped by the clamping terminal 44 is: the clamping portions 428 of the two clamping blocks 421 are in an everted state, and the clamping portions 428 of the two clamping blocks 421 are symmetrical with respect to the line connecting the first hinge portion 4421 and the linear driving mechanism 45. Since the length h of the first strip hole 4424 is not set to be too large, the pin 423 of the first hinge 4421 is located at the lower end of the first strip hole 4424 when the grip terminal 44 is in the initial state. When the clamping terminal 44 is clamping the workpiece, the clamping terminal 44 can only clamp the workpiece, but cannot clamp the workpiece and then translate the workpiece.
Referring to fig. 1 to 10, an insert clamping and positioning device for clamping an insert 1 and positioning the insert 1 at a preset position on the surface of a roller 2 comprises the clamping mechanism, wherein the clamping part 4428 is used for clamping the insert 1; the linear driving mechanism 45 is used for driving the clamping terminal 44 to move until the insert 1 abuts against the surface of the roller 2. The insert clamping and positioning device also comprises a slide rail 41 parallel to the axis of the roller 2; the horizontal distance direction between the roller 2 and the slide rail 41 is an X axis; the X axial distance between the clamping terminal 44 and the preset position of the roller 2 is configured to be a fixed value; the axial direction of the roller 2 is a Y axis; the clamping mechanism is slidably connected to the slide rail 41 and is used for driving the clamping terminal 44 to move along the Y axis to the Y axis of the roller 2 for positioning; the vertical distance direction between the roller 2 and the slide rail 41 is a Z axis; the output shafts of the linear drive mechanism 45 are distributed along the Z-axis.
In order to improve the positioning accuracy of the insert 1 and improve the installation efficiency of the insert 1, the technical scheme is provided with a roller insert welding device comprising a roller supporting mechanism 3, an insert clamping and positioning mechanism 4 and a roller rotary indexing mechanism 5, and the roller insert welding device is used for installing the insert 1 on the surface of a crusher roller 2.
In this implementation, roller supporting mechanism 3 is including the roller support 31 that is used for erectting roller 2, and this roller support 31 can be a pair of roller train, should roll to support in 2 axle heads of this roller to the roller train, and this roller supporting mechanism 3 still includes the guide rail, with this guide rail sliding connection's supporting seat, and every pair of roller train disposes a supporting seat, and the roller train sets up two gyro wheels for the level side by side, and this gyro wheel outer lane disposes the wear-resisting plastic layer of high strength to avoid damaging the outer lane of 2 axle heads of roller. And, to the roller 2 of different specifications, its axial length may be different, through two supporting seats of sliding along the guide rail to adjust the interval between should to the roller train, make should to the roller train can support the roller 2 of different axial lengths, make this technical scheme be applicable to the roller 2 of different specifications. It should be noted that, the support seat may be configured with a brake mechanism fixed to the guide rail to fix the position of the support seat, the brake mechanism may be a structure including an oil cylinder and a brake band-type brake, and the oil cylinder drives the brake band-type brake to clamp the guide rail to implement braking, the brake mechanism may also be a structure including a tightening bolt and a brake pad, and the tightening bolt is used to tighten the brake pad against the guide rail to implement braking; or the support base does not need to be provided with a brake mechanism fixed with the guide rail, because the cylinder shaft of the roller 2 is fixed with the dividing disc 51 in the roller rotary dividing mechanism 5, the axial positioning of the roller 2 takes the dividing disc 51 as a positioning reference, the roller support mechanism 3 only plays a role in radial positioning of the roller 2, the rotating speed of the roller 2 is slow in the rotating process, even if the support base in the roller support mechanism 3 has position deviation, the support base slightly slides along the guide rail, and the installation of the surface insert 1 of the roller 2 is not influenced.
In this embodiment, the insert clamping and positioning mechanism 4 comprises a slide rail 41 and a clamping mechanism, and the roller support 31 is arranged on a roller support 31, the clamping mechanism comprises a clamping terminal 44 for clamping the insert 1, and the insert clamping and positioning mechanism 4 is used for clamping the insert 1 and positioning the insert 1 on a preset position on the surface of the roller 2. The positioning of the insert 1 on the surface of the roll 2 is actually the positioning of the insert 1 in the X-axis direction, the Y-axis direction and the Z-axis direction with respect to the roll 2, and therefore the preset positions of the insert 1 on the surface of the roll 2 are actually: an X-axis position component, a Y-axis position component, and a Z-axis position component.
In order to determine the preset position of the insert 1 on the surface of the roller 2, the relative position between the slide rail 41 and the roller 2 needs to be determined, and further, the reference for positioning the insert 1 is determined, in the technical scheme, the roller support 31 is arranged on one roller support 31, one end of the slide rail 41 is provided with a positioning base 421, and the positioning base 421 is detachably connected with the roller support 31. The other end of the slide rail 41 is provided with an external base 422, a feeding space 43 is reserved between the external base 422 and the roller support 31, the external base 422 is detachably connected with the roller support 31 through a positioning base 421, so that the relative position of the slide rail 41 and the roller support 31 is determined, the relative position of the slide rail 41 and the roller 2 is determined when the position of the roller 2 and the roller support 31 is determined, and a reference is provided for the positioning of the insert 1 because the relative position of the slide rail 41 and the roller 2 is determined. In order to realize the loading of the insert 1, the other end of the sliding rail 41 is provided with the external base 422 according to the technical scheme, the external base 422 is separated from the roller support 31, a space is left between the external base 422 and the roller support 31 to serve as a loading space 43, when the insert 1 is clamped and held at the terminal 44, the clamping mechanism is moved to the loading space 43 to avoid the roller 2, and if the holding terminal 44 is right above the roller 2, the clamping of the insert 1 is not convenient because the gap between the roller 2 and the holding terminal 44 is small.

When the insert 1 needs to be clamped, the oil cylinder extends out of the piston rod, the piston rod pushes the slide block 4427 to move, the slide block 4427 drives the connecting rod 4429 to move, the connecting rod 4429 drives the clamping blocks 442 to rotate around the pin rod 4423, the pair of clamping blocks 442 is folded, and the pair of clamping blocks 442 clamps the insert 1.
In some embodiments, in the process that the insert 1 is clamped by the clamping terminal 44 and the insert 1 is moved to the surface of the drum 2, before the insert 1 reaches the preset position, in order to avoid the cut between the insert 1 to be mounted and the surface of the drum 2 or the interference between the insert 1 to be mounted and the installed insert 1, the insert 1 clamped by the clamping terminal 44 needs to be provided with a sufficient distance from the surface of the drum 2, and when the insert 1 is clamped by the clamping terminal 44 to the preset position, the linear driving mechanism 53 drives the clamping terminal 44 to be close to the surface of the drum 2 so as to enable the insert 1 to abut against the surface of the drum 2. In order to realize that the clamping terminal 44 can approach the surface of the roller 2 to make the insert 1 contact with the surface of the roller 2, in the present embodiment, the frame body 441 is provided with a first strip-shaped hole 4424, the length direction of the first strip-shaped hole 4424 is arranged in the output direction of the linear driving mechanism 53, and the pin 4423 is arranged in the first strip-shaped hole 4424; the frame body 441 is provided with a connecting point at a side thereof remote from the pair of clips 442, and a pre-tensioned elastic member 46 is provided between the connecting point and the pin 4423.

A positioning surface 4425 is arranged on one side of the pair of clamping blocks 442; when the pair of clips 442 are closed, the pair of positioning surfaces 4425 abut each other. The pre-tensioning elastic element 46 may be a tension spring or other elastic element capable of applying a pulling force to the pin 4423, and since the pin 4423 is under the pulling force of the pre-tensioning elastic element 46, when the insert 1 is not clamped, the pin 4423 is located at the upper end of the strip-shaped hole, and when the thrust value of the cylinder is greater than the pulling force value applied to the pin 4423 by the pre-tensioning elastic element 46 under the thrust action of the cylinder, the clamping block 442 and the pin 4423 slide downward integrally along the first strip-shaped hole 4424, so that the pin 4423 moves to the lower end of the strip-shaped hole. As shown in fig. 6, when the insert 1 is not clamped by the clamping terminal 44, the cylinder is in a piston rod retracting state, and the pair of clamping blocks 442 are opened by taking the pin 4423 as a rotation center under the driving of the tension of the pair of connecting rods 4429; when the insert 1 needs to be clamped, the insert 1 is placed in the clamping portion 4428 of the clamping block 442, the oil cylinder drives the oil cylinder to extend out of the piston rod, the piston rod drives the sliding block 4427 to slide along the sliding groove, the sliding block 4427 applies a pushing force to the connecting rod 4429, the pushing force value of the oil cylinder is smaller than the pulling force value applied to the pin rod 4423 by the pre-tensioning elastic piece 46, the pin rod 4423 is in a fixed state, the pair of connecting rods 4429 respectively drive the left clamping block 442 and the right clamping block 442 to rotate around the pin rod 4423, so that the pair of clamping blocks 442 rotate and close by the pin rod 4423, when the positioning surfaces 4425 of the two clamping blocks 442 are attached to each other, the pair of clamping blocks 442 are closed to the right, the clamping portions 4428 and the right clamping portion 4428 of the two clamping blocks 442 are closed to form a jaw, and the jaw clamps the insert 1, as shown in fig. 7. When the clamping mechanism slides to a preset position, the oil pump increases the oil pressure of the oil cylinder, increases the thrust force on the pair of connecting rods, and the thrust force value of the oil cylinder is greater than the tension force value applied to the pin 4423 by the pre-tensioning elastic piece 46, so that the clamping block 442 and the pin 4423 integrally slide downwards along the first strip-shaped hole 4424, the pin 4423 moves to the lower end of the first strip-shaped hole 4424, the insert 1 approaches the surface of the roller 2, the insert 1 is attached to the surface of the roller 2, and an operator can weld the insert 1 to the surface of the roller 2 conveniently, as shown in fig. 8.
It should be noted that, after the linear driving mechanism 45 drives the pair of blocks 421 to move for a distance H along the Z axis, the insert 1 abuts against a preset position on the surface of the roller 2, and the length H of the strip-shaped hole is greater than H.

In the process that the insert 1 is clamped by the clamping terminal 44 and the insert 1 is moved to the surface of the drum 21, before the insert 1 reaches the preset position, due to the arrangement of the first strip-shaped hole 4424, the insert 1 to be mounted and the surface of the drum 21 can be prevented from being scratched or the insert 1 to be mounted and the mounted insert 1 interfere with each other, so that a sufficient distance is left between the insert 1 clamped by the clamping terminal 44 and the surface of the drum 21. If H is less than H, the insert 1 cannot contact the surface of the roller 21; if H is equal to H, the insert 1 may have a clearance from the surface of the roll 21 due to the error, so that the insert 1 is easily detached during crushing after the insert 1 is welded to the roll 21.

In order to be suitable for the rollers 2 with different roller diameters, the sliding seat 47 is provided with a plurality of sets of mounting holes 471, when the rollers 2 with different roller diameters are replaced, in order to keep the H value relatively stable, the frame body 441 can be adjusted, so that the frame body 441 utilizes different mounting holes 471 to achieve the purpose of adjusting the H value, and the H value is kept relatively stable, so that the embodiment can be suitable for mounting the inserts 1 of the rollers 2 with different roller diameters.
When the pair of clamping blocks 442 clamp the insert 1, the oil pump needs to apply a large oil pressure to the oil cylinder in order to maintain the clamped state of the pair of clamping blocks 442. If the positioning surfaces 4425 of the two clamping blocks 442 are only just fitted by the oil pressure applied by the oil pump, the pressing force of the pair of clamping blocks 442 on the insert 1 is small, and is insufficient to stably clamp the insert 1. When the oil pump applies a large oil pressure to the oil cylinder, the technical scheme takes the joint of the respective positioning surfaces 4425 of the two clamping blocks 442 as a clamping reference, so that the left clamping block 442 and the right clamping block 442 are prevented from being continuously folded, and the clamping force of the left clamping block 442 and the right clamping block 442 for clamping the insert 1 is kept relatively stable. If the clamping blocks 442 are not provided with the positioning surfaces 4425, there is no structure for preventing the left clamping block 442 and the right clamping block 442 from continuing to close, and when the left clamping block 442 and the right clamping block 442 close, the oil pressure of the oil cylinder is applied to the insert 1 through the two clamping blocks 442 under the action of the oil cylinder, which may cause the insert 1 to be deformed by pressing or even damaged.
